In theory, they should be compatible with `$2b$` prefix. + +Compatibility with hashes generated by other languages is not 100% guaranteed due to difference in character encodings. However, it should not be an issue for most cases. + +### Migrating from v1.0.x + +Hashes generated in earlier version of `bcrypt` remain 100% supported in `v2.x.x` and later versions.

The value you submit is not just the number of rounds the module will go through to hash your data. The module will use the value you enter and go through `2^rounds` hashing iterations. + +From @garthk, on a 2GHz core you can roughly expect: + + rounds=8 : ~40 hashes/sec + rounds=9 : ~20 hashes/sec + rounds=10: ~10 hashes/sec + rounds=11: ~5 hashes/sec + rounds=12: 2-3 hashes/sec + rounds=13: ~1 sec/hash + rounds=14: ~1.5 sec/hash + rounds=15: ~3 sec/hash + rounds=25: ~1 hour/hash + rounds=31: 2-3 days/hash + + +## A Note on Timing Attacks + +Because it's come up multiple times in this project and other bcrypt projects, it needs to be said. The `bcrypt` library is not susceptible to timing attacks. From codahale/bcrypt-ruby#42: + +> One of the desired properties of a cryptographic hash function is preimage attack resistance, which means there is no shortcut for generating a message which, when hashed, produces a specific digest. + +A great thread on this, in much more detail can be found @ codahale/bcrypt-ruby#43 + +If you're unfamiliar with timing attacks and want to learn more you can find a great writeup @ [A Lesson In Timing Attacks][timingatk] + +However, timing attacks are real. And the comparison function is _not_ time safe. That means that it may exit the function early in the comparison process. Timing attacks happen because of the above. We don't need to be careful that an attacker will learn anything, and our comparison function provides a comparison of hashes. It is a utility to the overall purpose of the library. If you end up using it for something else, we cannot guarantee the security of the comparator. Keep that in mind as you use the library. + +## Hash Info + +The characters that comprise the resultant hash are `./ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789$`. + +Resultant hashes will be 60 characters long and they will include the salt among other parameters, as follows: + +`$[algorithm]$[cost]$[salt][hash]` + +- 2 chars hash algorithm identifier prefix. `"$2a$" or "$2b$"` indicates BCrypt +- Cost-factor (n).

Use of this class +/// depends somewhat on whether C++ exceptions are enabled at compile time. +/// +/// ### Handling Errors With C++ Exceptions +/// +/// If C++ exceptions are enabled, then the `Error` class extends +/// `std::exception` and enables integrated error-handling for C++ exceptions +/// and JavaScript exceptions. +/// +/// If a Node-API call fails without executing any JavaScript code (for +/// example due to an invalid argument), then the Node-API wrapper +/// automatically converts and throws the error as a C++ exception of type +/// `Napi::Error`. Or if a JavaScript function called by C++ code via Node-API +/// throws a JavaScript exception, then the Node-API wrapper automatically +/// converts and throws it as a C++ exception of type `Napi::Error`. +/// +/// If a C++ exception of type `Napi::Error` escapes from a Node-API C++ +/// callback, then the Node-API wrapper automatically converts and throws it +/// as a JavaScript exception. Therefore, catching a C++ exception of type +/// `Napi::Error` prevents a JavaScript exception from being thrown. +/// +/// #### Example 1A - Throwing a C++ exception: +/// +/// Napi::Env env = ... +/// throw Napi::Error::New(env, "Example exception"); +/// +/// Following C++ statements will not be executed. The exception will bubble +/// up as a C++ exception of type `Napi::Error`, until it is either caught +/// while still in C++, or else automatically propagated as a JavaScript +/// exception when the callback returns to JavaScript. +/// +/// #### Example 2A - Propagating a Node-API C++ exception: +/// +/// Napi::Function jsFunctionThatThrows = someObj.As(); +/// Napi::Value result = jsFunctionThatThrows({ arg1, arg2 }); +/// +/// Following C++ statements will not be executed. The exception will bubble +/// up as a C++ exception of type `Napi::Error`, until it is either caught +/// while still in C++, or else automatically propagated as a JavaScript +/// exception when the callback returns to JavaScript. +/// +/// #### Example 3A - Handling a Node-API C++ exception: +/// +/// Napi::Function jsFunctionThatThrows = someObj.As(); +/// Napi::Value result; +/// try { +/// result = jsFunctionThatThrows({ arg1, arg2 }); +/// } catch (const Napi::Error& e) { +/// cerr << "Caught JavaScript exception: " + e.what(); +/// } +/// +/// Since the exception was caught here, it will not be propagated as a +/// JavaScript exception. +/// +/// ### Handling Errors Without C++ Exceptions +/// +/// If C++ exceptions are disabled (by defining +/// `NODE_ADDON_API_DISABLE_CPP_EXCEPTIONS`) then this class does not extend +/// `std::exception`, and APIs in the `Napi` namespace do not throw C++ +/// exceptions when they fail. Instead, they raise _pending_ JavaScript +/// exceptions and return _empty_ `Value`s. Calling code should check +/// `Value::IsEmpty()` before attempting to use a returned value, and may use +/// methods on the `Env` class to check for, get, and clear a pending JavaScript +/// exception. If the pending exception is not cleared, it will be thrown when +/// the native callback returns to JavaScript. +/// +/// #### Example 1B - Throwing a JS exception +/// +/// Napi::Env env = ... +/// Napi::Error::New(env, "Example +/// exception").ThrowAsJavaScriptException(); return; +/// +/// After throwing a JS exception, the code should generally return +/// immediately from the native callback, after performing any necessary +/// cleanup. +/// +/// #### Example 2B - Propagating a Node-API JS exception: +/// +/// Napi::Function jsFunctionThatThrows = someObj.As(); +/// Napi::Value result = jsFunctionThatThrows({ arg1, arg2 }); +/// if (result.IsEmpty()) return; +/// +/// An empty value result from a Node-API call indicates an error occurred, +/// and a JavaScript exception is pending. To let the exception propagate, the +/// code should generally return immediately from the native callback, after +/// performing any necessary cleanup. +/// +/// #### Example 3B - Handling a Node-API JS exception: +/// +/// Napi::Function jsFunctionThatThrows = someObj.As(); +/// Napi::Value result = jsFunctionThatThrows({ arg1, arg2 }); +/// if (result.IsEmpty()) { +/// Napi::Error e = env.GetAndClearPendingException(); +/// cerr << "Caught JavaScript exception: " + e.Message(); +/// } +/// +/// Since the exception was cleared here, it will not be propagated as a +/// JavaScript exception after the native callback returns. +class Error : public ObjectReference +#ifdef NODE_ADDON_API_CPP_EXCEPTIONS + , + public std::exception +#endif // NODE_ADDON_API_CPP_EXCEPTIONS +{ + public: + static Error New(napi_env env);

+The clang-format checking tools is designed to check changed lines of code compared to given git-refs. + +## Migration Script + +The migration tool is designed to reduce repetitive work in the migration process. However, the script is not aiming to convert every thing for you. There are usually some small fixes and major reconstruction required. + +### How To Use + +To run the conversion script, first make sure you have the latest `node-addon-api` in your `node_modules` directory. +``` +npm install node-addon-api +``` + +Then run the script passing your project directory +``` +node ./node_modules/node-addon-api/tools/conversion.js ./ +``` + +After finish, recompile and debug things that are missed by the script. + + +### Quick Fixes +Here is the list of things that can be fixed easily. + 1. Change your methods' return value to void if it doesn't return value to JavaScript. + 2. Use `.` to access attribute or to invoke member function in Napi::Object instead of `->`. + 3. `Napi::New(env, value);` to `Napi::[Type]::New(env, value); + + +### Major Reconstructions +The implementation of `Napi::ObjectWrap` is significantly different from NAN's. `Napi::ObjectWrap` takes a pointer to the wrapped object and creates a reference to the wrapped object inside ObjectWrap constructor. `Napi::ObjectWrap` also associates wrapped object's instance methods to Javascript module instead of static methods like NAN. + +So if you use Nan::ObjectWrap in your module, you will need to execute the following steps. + + 1. Convert your [ClassName]::New function to a constructor function that takes a `Napi::CallbackInfo`. Declare it as +``` +[ClassName](const Napi::CallbackInfo& info); +``` +and define it as +``` +[ClassName]::[ClassName](const Napi::CallbackInfo& info) : Napi::ObjectWrap<[ClassName]>(info){ + ... +} +``` +This way, the `Napi::ObjectWrap` constructor will be invoked after the object has been instantiated and `Napi::ObjectWrap` can use the `this` pointer to create a reference to the wrapped object. + + 2. Move your original constructor code into the new constructor. Delete your original constructor. + 3. In your class initialization function, associate native methods in the following way. +``` +Napi::FunctionReference constructor; + +void [ClassName]::Init(Napi::Env env, Napi::Object exports, Napi::Object module) { + Napi::HandleScope scope(env); + Napi::Function ctor = DefineClass(env, "Canvas", { + InstanceMethod<&[ClassName]::Func1>("Func1"), + InstanceMethod<&[ClassName]::Func2>("Func2"), + InstanceAccessor<&[ClassName]::ValueGetter>("Value"), + StaticMethod<&[ClassName]::StaticMethod>("MethodName"), + InstanceValue("Value", Napi::[Type]::New(env, value)), + }); + + constructor = Napi::Persistent(ctor); + constructor .SuppressDestruct(); + exports.Set("[ClassName]", ctor); +} +``` + 4. In function where you need to Unwrap the ObjectWrap in NAN like `[ClassName]* native = Nan::ObjectWrap::Unwrap<[ClassName]>(info.This());`, use `this` pointer directly as the unwrapped object as each ObjectWrap instance is associated with a unique object instance. + + +If you still find issues after following this guide, please leave us an issue describing your problem and we will try to resolve it. diff --git a/node_modules/node-addon-api/tools/check-napi.js b/node_modules/node-addon-api/tools/check-napi.js new file mode 100644 index 0000000..9199af3 --- /dev/null +++ b/node_modules/node-addon-api/tools/check-napi.js @@ -0,0 +1,99 @@ +'use strict'; +// Descend into a directory structure and, for each file matching *.node, output +// based on the imports found in the file whether it's an N-API module or not. + +const fs = require('fs'); +const path = require('path'); + +// Read the output of the command, break it into lines, and use the reducer to +// decide whether the file is an N-API module or not. +function checkFile (file, command, argv, reducer) { + const child = require('child_process').spawn(command, argv, { + stdio: ['inherit', 'pipe', 'inherit'] + }); + let leftover = ''; + let isNapi; + child.stdout.on('data', (chunk) => { + if (isNapi === undefined) { + chunk = (leftover + chunk.toString()).split(/[\r\n]+/); + leftover = chunk.pop(); + isNapi = chunk.reduce(reducer, isNapi); + if (isNapi !== undefined) { + child.kill(); + } + } + }); + child.on('close', (code, signal) => { + if ((code === null && signal !== null) || (code !== 0)) { + console.log( + command + ' exited with code: ' + code + ' and signal: ' + signal); + } else { + // Green if it's a N-API module, red otherwise. + console.log( + '\x1b[' + (isNapi ?
