Frequently Asked Questions

Which SHA algorithm should I use?

SHA-256 is the most widely used and recommended for general purposes. SHA-512 provides stronger security. SHA-1 is deprecated and should only be used for legacy compatibility.

Is SHA hashing reversible?

No. SHA is a one-way cryptographic hash function. You cannot reverse a SHA hash to get the original input.
