  • MD5
    128-bit Deprecated
    Message-Digest Algorithm 5

    Fast 128-bit hash. Widely used for file checksums and data deduplication. Cryptographically broken - susceptible to collision and length-extension attacks. Do not use for passwords or digital signatures.

  • SHA-1
    160-bit Deprecated
    Secure Hash Algorithm 1

    160-bit hash standardized by NIST. Deprecated since 2011 due to collision attacks. Still found in Git commit IDs, legacy TLS, and older certificate chains. Do not use for new security-sensitive applications.

  • SHA-256
    256-bit Secure
    Secure Hash Algorithm 256-bit (SHA-2)

    The most widely deployed secure hash in active use. Part of the SHA-2 family. Used in TLS certificates, Bitcoin proof-of-work, JWT (HS256 / RS256), code signing, and file integrity verification.

  • SHA-384
    384-bit Secure
    Secure Hash Algorithm 384-bit (SHA-2)

    A truncated variant of SHA-512 with independent initial values. Produces 384 bits of output. Common in TLS 1.2 cipher suites requiring higher security margins and in government-grade applications.

  • SHA-512
    512-bit Secure
    Secure Hash Algorithm 512-bit (SHA-2)

    Largest SHA-2 variant, operating on 64-bit words. 512-bit output makes pre-image attacks computationally infeasible. Used in PBKDF2, bcrypt wrappers, blockchain, and high-security digital signatures.
