About these hash algorithms

SHA-256 is the most widely used — it produces a 64-character hex string and is used in TLS certificates, Git commits, Bitcoin, and file integrity verification.

SHA-1 (40 chars) is considered weak for security but is still used in Git for object hashing. SHA-512 (128 chars) provides the strongest collision resistance.

All hashing is done using the browser's built-in crypto.subtle.digest() API. No data leaves your machine.
