A cryptographic hash function takes an input of any size and produces a fixed-size output called a digest. These functions are designed to be one-way: it is computationally infeasible to reverse the hash and recover the original input.
SHA-1
SHA-1 produces a 160-bit hash. While still used for non-security purposes like checksums, it is considered cryptographically weak and should not be used for security-critical applications.
SHA-256
Part of the SHA-2 family, SHA-256 produces a 256-bit hash and is widely used in SSL/TLS certificates, Bitcoin mining, and data integrity verification. It is currently considered secure.
SHA-512
Also part of SHA-2, SHA-512 produces a 512-bit hash. It offers stronger collision resistance and is often used when extra security margin is desired.
