When you send your transaction (request for subscription, purchase of a product) to our made safe system, this transaction must be accompanied by a encrypted signature, for obvious reasons of safety.
Encoding selected is the encoding "MD5", recognized for its robustness.

What is MD5 ?

The message digest algorithm was developed by Professor Ronald L. Rivest of MIT. 'The MD5 algorithm is intended for digital signature applications, where a large file must be "compressed" in a secure manner before being encrypted with a private (secret) key under a public-key cryptosystem such as RSA.' MD5 is a hash, i.e it is not reversible without a lot of effort (probably about a year and a half on a 1ghz athlon).
