Frequently Asked Questions

What is hashing vs encryption?

Hashing is a one-way function that produces a fixed-size digest. It is not encryption, which is reversible. Hashes are used for integrity verification, not confidentiality.

Is SHA-1 still secure?

SHA-1 is considered cryptographically weak and should not be used for security purposes. We include it for compatibility but recommend SHA-256 or SHA-512.
