Frequently Asked Questions
Which hash algorithm should I use?
SHA-256 is recommended for most purposes. MD5 and SHA-1 are considered cryptographically broken and should only be used for non-security checksums.
Can a hash be reversed?
No, cryptographic hash functions are one-way. You cannot derive the original input from a hash value.
What is HMAC?
HMAC (Hash-based Message Authentication Code) combines a hash function with a secret key to verify both data integrity and authenticity.
