About Hash Functions

MD5 produces a 128-bit hash. It's fast and widely used for checksums, but is no longer considered secure for cryptographic purposes due to known collision vulnerabilities.

SHA-1 produces a 160-bit hash. It was the industry standard for many years but has been deprecated for security use since 2017.

SHA-256 is part of the SHA-2 family and produces a 256-bit hash. It's the current standard for most security applications including Bitcoin and TLS certificates.

SHA-512 produces a 512-bit hash. It offers higher security margin than SHA-256 and can be faster on 64-bit processors.
