Crypto

Compute SHA-1, SHA-256, SHA-384, or SHA-512 digests of text or file bytes.

• Hash bytesHash a text string with SHA-1 / SHA-256 / SHA-384 / SHA-512.
• Hash fileHash arbitrary file bytes with SHA-1 / SHA-256 / SHA-384 / SHA-512.
• HMAC signCompute an HMAC signature (SHA-1/256/384/512) over input bytes.
• HMAC verifyVerify an HMAC signature in constant time.

Round-trip strings or binary blobs through base64 (standard or URL-safe) and hex.

• Base64 decodeDecode a base64 string to its original bytes.
• Base64 encodeEncode bytes as base64.
• Hex decodeDecode a hexadecimal string to its original bytes.
• Hex encodeEncode bytes as a hexadecimal string.

Sign, verify, and decode JSON Web Tokens (HS256 / HS384 / HS512).

• JWT decodeDecode a JSON Web Token without verifying it. Returns header + payload + claims.
• JWT signSign a JWT (HS256 / HS384 / HS512).
• JWT verifyVerify a JWT signature and return the decoded claims.

Cryptographically random UUIDs, opaque tokens, and human-friendly passwords.

• Password generateGenerate cryptographically random passwords with configurable length and character classes.
• Token generateGenerate cryptographically random tokens (hex, base64url, etc.).
• UUID generateGenerate a UUID (v4 random or v7 time-ordered).
