Symmetric Encryption

Advanced Encryption Standard (AES)

A widely used symmetric encryption algorithm that operates on fixed-size data blocks and provides strong security through multiple rounds of substitution and permutation.

Twofish

A symmetric encryption algorithm known for strong security and efficient performance, commonly used in applications like disk encryption.

Data Encryption Standard (DES)

An early symmetric encryption algorithm that encrypts 64-bit data blocks using a 56-bit key; now considered outdated and replaced by more secure methods like AES.

RC5

A symmetric block cipher (Rivest Cipher) that uses variable block sizes, key lengths, and number of rounds for flexible encryption.

RC6

A symmetric block cipher based on RC5, enhanced with additional features to provide stronger security and improved performance.

CAST-128

A symmetric block cipher developed by Carlisle Adams and Stafford Tavares, known for its simplicity and reliable encryption for secure communications.

Triple Data Encryption Standard (3DES)

An improved version of DES that applies the encryption process three times to increase security.

Blowfish

A fast and flexible symmetric encryption algorithm designed for efficient encryption and decryption in various applications.

RC4

A symmetric stream cipher that generates a pseudorandom stream of bits; once widely used but now deprecated due to security vulnerabilities.

Salsa20

A family of fast symmetric stream ciphers designed for secure encryption in both hardware and software.

ChaCha20

A more secure variant of Salsa20 that provides strong, efficient stream cipher encryption and resistance to certain attacks.
