About Encryption Algorithms

AES-256 (Advanced Encryption Standard)

AES is a symmetric encryption algorithm widely used across the globe. AES-256 uses a 256-bit key size, making it extremely secure against brute-force attacks. It's the standard encryption algorithm used by the U.S. government.

Blowfish

Blowfish is a symmetric block cipher that can be used as a drop-in replacement for DES or IDEA. It's unpatented, free to use, and has been extensively analyzed for vulnerabilities.

Triple DES (3DES)

Triple DES applies the DES cipher algorithm three times to each data block. While not as secure as AES, it's still used in some financial applications and legacy systems.

RC4

RC4 is a stream cipher known for its simplicity and speed. While it's been widely used in protocols like SSL and WEP, it's now considered insecure for many applications.

Base64

Base64 is an encoding scheme that represents binary data in an ASCII string format. While not encryption, it's often used to encode encrypted data for transmission.

Hashing Algorithms (MD5, SHA-1, SHA-256)

Hash functions produce a fixed-size output (hash value) from variable-size input. They're one-way functions and cannot be decrypted. Useful for verifying data integrity.
