Last updated on Feb 7, 2006 with the following description: FindCrypt now works with both little and big endian programs. It knows to reuse old slots in the bookmarks if run repeatedly. It is fully automatic and scans each new created database. Manual scan is still available.

Description
While analyzing a program quite often we want to know if it uses any crypto algorithm. Knowing the algorithm name would be useful too. Here is the plugin which can help us answer these questions.

The idea behind it pretty simple: since almost all crypto algorithms use magic constants, we will just look for these constants in the program body.

The plugin supports virtually all crypto algorithms and hash functions. I also added the zlib library constants to the list just for the user convenience. Here is the full list:

* Blowfish
* Camellia
* CAST
* CAST256
* CRC32
* DES
* GOST
* HAVAL
* MARS
* MD2
* MD4
* MD5
* PKCS_MD2 (byte sequence used in PKCS envelope)
* PKCS_MD5 (byte sequence used in PKCS envelope)
* PKCS_RIPEMD160 (byte sequence used in PKCS envelope)
* PKCS_SHA256 (byte sequence used in PKCS envelope)
* PKCS_SHA384 (byte sequence used in PKCS envelope)
* PKCS_SHA512 (byte sequence used in PKCS envelope)
* PKCS_Tiger (byte sequence used in PKCS envelope)
* RawDES
* RC2
* RC5
* RC6
* Rijndael
* SAFER
* SHA-1
* SHA-256
* SHA-512
* SHARK
* SKIPJACK
* Square
* Tiger
* Twofish
* WAKE
* Whirlpool
* zlib

Please note that the list does not contain the IDEA algorithm because it usually builds its tables on the fly. Other algorithms can be added if needed.
