Supported Algorithms

Cryptix includes the following algorithms. See below for Notes and Colour Codes.

Symmetric Ciphers

Name Status Conforms Comments
Blowfish Supported
CAST5 Supported RFC-2144
DES Supported
DES-EDE3 Supported SSLeay 0.8.1 This is 3-key Triple DES.
No known conformance data,
checked against SSLeay only,
needs more comparisons
IDEA Supported
LOKI91 Supported
RC2 Supported
RC4 Supported
SAFER Supported De Moliner95
SPEED Supported Zheng97
Square Supported ? source of test data unknown?

Cipher Modes

Name Status Comments
ECB Supported
CBC Supported
CFB Supported
OFB Supported
PCBC Supported
CFB-PGP Supported Special CFB mode for PGP

Padding Schemes

Name Status Comments
PKCS#5 Supported
PKCS#7 Supported
OneAndZeroes Supported

Asymmetric (public-key) Ciphers

Name Status Comments
RSA Supported
ElGamal Supported

Signature Schemes

MD x Algorithm x Padding
MD2 RSA PKCS#1
MD5 ElGamal
SHA-1 RPK
RIPEMD160
SHA-1 DSAJCA PKCS#1

This table indicates that a signature scheme of md/alg/PKCS#1 is possible, where md and alg are as listed above.

JCA The DSA signature algorithm is as provided with the JCA in Sun's JDK. As supplied, the scheme only provides SHA-1/DSA/PKCS#1

Message Digests

Name Status Conforms Comments
HAVAL Supported Zheng93
MD2 Supported RFC-1319
MD4 Supported RFC-1320
MD5 JCA Supported RFC-1321 bug in update() method 3.0.3 and before
RIPEMD128 Supported Dobbertin96
RIPEMD160 Supported Dobbertin96
SHA-1JCA Supported FIPS 180-1 bug in update() method 3.0.3 and before
SHA-0 Supported FIPS 180 bug in update() method 3.0.3 and before
algorithm deprecated by SHA-1

JCA MD5 and SHA-1 are also supplied with the JCA in Sun's JDK.

All message digests now include HMAC support, according to RFC-2104 and RFC-2202.

Notes

These notes apply:

Colour Coding Scheme

Colour Code for Status
Heading
Only
Good
Tested.
Expected OK
Not fully tested
Warning!
Known Problems
Take Care
Dead!
Not Working.

These colours are indicative. See the code for precise information.

Colour Code for Conformance
Conforms
against validated data
OK
No formal data,
but well accepted data used instead
Checked
No data exists
but checks against other implementations are OK.
Warning!
Some data sets fail
Take Care
Dead!
All Data Fails

Conformance is stated strictly against authoritive data sets, most likely published by the author. Reference must be included.

With older algorithms, where no conformance data has ever been published, but widely accepted data exist, this is listed as OK.
