Symmetric Encryption Algorithms

Advanced Encryption Standard (AES)

A block cipher recommended by NIST to replace DES. Brute force attack is the only effective attack known against it, in which the attacker tries to test all the characters combinations to unlock the encryption.

Blowfish

Blowfish is a variable length key, 64-bit block cipher, one of the most common public domain encryption algorithms provided by Bruce Schneier.

Data Encryption Standard (DES)

There are many attacks and methods to exploit it, which makes it an insecure block cipher.

3DES

3DES is an enhancement of DES, where the encryption method is similar to the one in original DES but applied three times to increase the encryption level. 3DES is slower than other block cipher methods.
