[fpc-pascal] Hashes and CRCs

[Mark Morgan Lloyd]

Noting discussion of a couple of weeks ago re. HMAC_SHA1 and FPC's hash 
package, I've just been hunting for Tiger and have found 
http://www.cityinthesky.co.uk/opensource/DCPcrypt which looks interesting:

Encryption Algorithms  Hash Algorithms
Blowfish               Haval
Cast 128               MD4
Cast 256               MD5
DES, 3DES              RipeMD-128
Ice, Thin Ice, Ice2    RipeMD-160
IDEA                   SHA-1
Mars                   SHA-256, SHA-384, SHA-512
Misty1                 Tiger
RC2, RC4, RC5, RC6 	
Rijndael (the AES) 	
Serpent 	
Tea 	
Twofish 	

Also, anybody doing traditional datacomms work might find crcm_cat.pas 
and crcmodel.pas from 
http://www.wolfgang-ehrhardt.de/crc_hash_2013-01-07.zip useful, there's 
times I'd have murdered for a decent 4-bit CRC to fit a gap in a header. 
Same author also has implementation of other crypto and hash stuff 
including Skipjack, all believed good for FPC
