A Dart library implementing cryptographic algorithms

Pointy Castle #

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 Pointy Castle.

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

Block ciphers:

  • AES

Asymmetric block ciphers:

  • RSA

Stream ciphers:

  • Salsa20

Block cipher modes of operation:

  • CBC (Cipher Block Chaining mode)
  • CFB (Cipher Feedback mode)
  • ECB (Electronic Code Book mode)
  • GCTR (GOST 28147 OFB counter mode)
  • OFB (Output FeedBack mode)
  • CTR (Counter mode)
  • SIC

Paddings:

  • PKCS7

Digests:

  • MD2
  • MD4
  • MD5
  • RIPEMD-128
  • RIPEMD-160
  • RIPEMD-256
  • RIPEMD-320
  • SHA-1
  • SHA-224
  • SHA-256
  • SHA-3
  • SHA-384
  • SHA-512
  • SHA-512/t
  • Tiger
  • Whirlpool

MACs:

  • HMAC

Signatures:

  • (DET-)ECDSA
  • RSA

Password based key derivators:

  • PBKDF2
  • scrypt

Asymmetric key generators:

  • ECDSA
  • RSA

Secure PRNGs:

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