A cryptographic algorithm, also called a cipher, is the mathematical function used for encryption and decryption. The program uses extremely secure algorithms.

SHA1 One-Way Hash Function
Security of embedded passwords is provided through the SHA1 one-way hash function. A one-way hash function operates on a message of arbitrary length to produce a hash value of fixed length. The hash cannot be reversed to recreate the message, thus, it is considered to be one-way.

Blowfish 448
Blowfish is a variable-length key, 64-bit block cipher. The program uses a 16 round Blowfish implementation with a full-length 448-bit key.

Twofish
Twofish builds on Blowfish and is designed to be highly secure and highly flexible. The program uses Twofish with a 256-bit key.

Rijndael
Rijndael is a block cipher. The program uses Rijndael with a 256-bit key.

Cast-128
CAST-128 is a 12- or 16-round Feistel cipher that has a block size of 64 bits and a key size of up to 128 bits.

GOST
GOST (full name is GOST28147-89) is not widely known, but believed to be strong. The size of the GOST key is 256 bits.
