To keep passwords secure, Access Manager uses 'strong' encryption algorithms.  Strength is often measured in the number of bits used for the encryption key.  Many systems commonly use between 64 and 256 bits.  Most cryptographers consider 128 bits to be strong enough to take a very powerful computer many years to break.

Access Manager uses dual encryption that includes both 'Blowfish' and 'Rijndael' with 256 bits each.

Blowfish was invented by Bruce Schneier, an internationally renowned security technologist and author.  In 1993 he put Blowfish in the public domain, offering it unpatented and royalty-free.  As far as is known, Blowfish encryption has never been compromised or broken.  For more information on Blowfish visit www.schneier.com/blowfish.html.

Rijndael is the Advanced Encryption Standard (AES) recommended for use within US government organisations.  For more information on Rijndael visit www.nist.gov/public_affairs/releases/aesq&a.htm.
