Compute SHA-256, SHA-384 or SHA-512 for a file and compare an expected checksum.

Encrypt or decrypt a file using AES-256-GCM with a password-derived key and authenticated metadata.

Compute SHA-256, SHA-384 or SHA-512 over the exact UTF-8 bytes of your text.

Calculate an HMAC over exact UTF-8 text using a secret key and a SHA-2 algorithm.
