Algorithm Implementation

The following text describes the specifications/requirements for each of the supported algorithms.

RC4 - Rivest Cipher 4: Wiki

  • Key Length: Typically 40-256 bits (5-32 bytes)
  • Block Size: NA
  • Mode: NA

  • This is the simplest and fastest of the supported algorithms and is the algorithm currently used by Comet-16 and is the default algorithm used by Comet-32. See Encrypt/Decrypt

3DES - Triple Data Encryption Standard: Wiki

  • Key Length: 168 bits although 192 bits (24 bytes) must be supplied (parity bits are discarded).
  • Block Size: 8 Bytes
  • Mode: CBC - Introduces feedback by combining ciphertext and plaintext
  • IV Required: Yes

AES - Advanced Encryption Standard: Wiki

  • Key Length: 128, 192, 256 bits
  • Block Size: 16 Bytes
  • Mode: CBC - Introduces feedback by combining ciphertext and plaintext
  • IV Required: Yes
