Generate secure hash values with various hashing algorithms

MD5 Hash

Message Digest Algorithm 5

MD5 produces a 128-bit (16-byte) hash value. While no longer considered secure for cryptographic purposes, it's still useful for checksums and data verification.

SHA1 Hash

Secure Hash Algorithm 1

SHA1 produces a 160-bit (20-byte) hash value. While deprecated for security applications, it's still used for version control systems and data integrity checks.

SHA2 Hash

Secure Hash Algorithm 2

SHA2 includes multiple hash functions (SHA-224, SHA-256, SHA-384, SHA-512) with different output sizes. Widely used for secure applications and digital signatures.

SHA3 (Keccak)

Secure Hash Algorithm 3

SHA3 is the latest member of the SHA family, standardized by NIST in 2015. Based on the Keccak algorithm, it uses a different internal structure called a sponge construction.

BLAKE2

Fast and secure hash function

BLAKE2 is faster than MD5, SHA-1, SHA-2, and SHA-3, yet is at least as secure as SHA-3. Available in two variants: BLAKE2b (64-bit) and BLAKE2s (32-bit).

BLAKE3

Next-generation hash function

BLAKE3 is much faster than previous hash functions and maintains high security. It supports parallel computation and can produce outputs of any length.

Argon2

Password hashing function

Argon2 is the winner of the Password Hashing Competition (2015). It's designed specifically for password hashing and comes in three variants: Argon2i, Argon2d, and Argon2id.
