The goal of this module is to reimplement node's crypto module,
|
|
10
|
in pure javascript so that it can run in the browser.
|
|
11
|
|
|

|
Here is the subset that is currently implemented:
|
|
13
|
|
|

|
* createHash (sha1, sha224, sha256, sha384, sha512, md5, rmd160)
|
|
15
|
* createHmac (sha1, sha224, sha256, sha384, sha512, md5, rmd160)
|
|

|
* pbkdf2
|
|
17

* pbkdf2Sync
|
|
18
|
* randomBytes

|
* pseudoRandomBytes
|
|
20
|
* createCipher (aes)

|
22

## contributions
|
|

|
|
|
37
|
If you are interested in writing a feature, please implement as a new module,
|
|
38
|
which will be incorporated into crypto-browserify as a dependency.
|
|
39
|
|
|
40
|
All deps must be compatible with node's crypto
|
|
41
|
(generate example inputs and outputs with node,
|
|
42
|
and save base64 strings inside JSON, so that tests can run in the browser.

|
Crypto is _extra serious_ so please do not hesitate to review the code,
|
|
46
|
and post comments if you do.
