Fast (de)crypting with symmetric key 4 Kb
This is my first try in cryptography. It is very fast and simple, but easy breakable as the number of zeroes and ones doesn't change - they are simply reordered.
Computing the hash function RIPEMD-160 12 Kb
This is a hash function, which makes an extraction of size 160 bits from the input datas (not larger than 4 Gb), and with the help of these extractions we can see whether 2 input series differ, without comparing 50 Mb for example. It is very difficult to obtain the input seria from the 160-bit extraction.
MD5 message digest 8 Kb
This is another hash function, which returns 512-bits extraction and is widely used in communications.
PGP 2.63 1.8 Мb
Pretty good privacy version 2.63 source code (in C) - the following algorythms are included:
The Blow Fish algorhythm 33 Kb
Blow fish is an encryption algorhythm working on blocks of 64 bits, so that a confidential correspondence can be carried out, and is rather fast - about 30 Kb/s on old 386DX/33 MHz.
Several routines by Robert Durnal 169 Kb
These are several crypting routines, which a friend of mine asked me to host. He is a 74 year old retired man, living in USA. He is interested in cryptography, steganography, programming in Assembler. His web-page is "http://www.afn.org/~afn21533/". Here I'm providing with his permission several routines:
