The characteristics, security status, use cases, and examples of each hash and checksum algorithm

Compare the algorithms supported by AG HASH at a glance. Click a card to see each algorithm's bit length, security status, a real example hash, and its ideal use cases.
MD5
128-bit checksum — fast, but unfit for security
Legacy 128-bit
CRC32
32-bit cyclic redundancy check — detects transmission errors
Checksums 32-bit
SHA-1
160-bit — an older secure hash, now effectively retired
Legacy 160-bit
SHA-256
256-bit — the most widely used standard secure hash
Secure hashes 256-bit
SHA-384
384-bit — a truncated SHA-512 with a wide security margin
Secure hashes 384-bit
SHA-512
512-bit — the longest standard SHA-2 hash
Secure hashes 512-bit
HMAC
Key-based message authentication code (HMAC-SHA)
