Symmetric & Asymmetric Key Algorithms

RSA

Widely used for secure data transmission and digital signatures.

ECC

More efficient than RSA, using smaller keys for the same security level.

SHA-2

A cryptographic hash function for data integrity.

ECDSA

Digital signatures based on elliptic curves, offering efficiency and security.

DSS

A standard for digital signatures, often using DSA and hash functions.

Block Cipher

Encrypt data in fixed-size blocks (e.g., 64 bits, 128 bits).

Stream Cipher

Encrypt data one bit or byte at a time.

AES

A strong and secure block cipher, widely used for encrypting data in fixed blocks; block size - 128 bits; key sizes - 128, 192, or 256 bits.

DES

An older block cipher now considered insecure due to its short key length; block size - 64 bits; key size - 56 bits (presented as 64, 8 bits for parity).

RC4

A fast stream cipher with a variable key size (between 40-2048 bits) but has known vulnerabilities; less used today.

SALSA20

A modern, fast stream cipher known for its efficiency and security; key size - 256 bits (with a 64-bit nonce).
