cipher

0.5.0

A Dart library implementing cryptographic algorithms.

Readme

cipher

A Dart library for encryption and decryption. As of today, most of the classes are ports of Bouncy Castle from Java to Dart. The porting is almost always direct except for some classes that had been added to ease the use of low level data.

To make sure nothing fails, tests and benchmarks for every algorithm are provided. The expected results are taken from the Bouncy Castle Java version and also from standards, and matched against the results got from cipher.

As of the last release, the following algorithms are implemented:

Block ciphers:

AES (fast version)

Stream ciphers:

Salsa 20

Block cipher modes of operation:

SIC (a.k.a. CTR)
CBC

Paddings:

PKCS7

Digests:

RIPEMD-160
SHA-1
SHA-256

MACs:

HMAC

Signatures:

ECDSA

Password based key derivators:

PBKDF2
scrypt

Asymmetric key generators:

ECDSA

Entropy sources (true RNGs):

URL based (can be used, for example, with random.org)
File based (can be used, for example, with /dev/random)

Secure PRNGs:

Based on block cipher in CTR mode
Based on block cipher in CTR mode with auto reseed (for forward security)
