Cryptographic Hash Functions: Verification of File Checksums, Integrity, and SHA-256 Hashes

What is a Cryptographic Hash Function?

A cryptographic hash function takes an input string of any length and converts it into a fixed-size string of hexadecimal characters. Cryptographic hashes are one-way functions: it is computationally impossible to invert a hash back into original input data.

Common Hash Algorithms

• MD5: 128-bit hash string. Used for non-cryptographic checksum verification.
• SHA-256: 256-bit hash algorithm widely used in SSL certificates, Git commits, and Bitcoin mining.
• SHA-512: 512-bit high-security hashing algorithm for enterprise security applications.
