Hash Generator vs JWT Decoder

cryptography

Hash Generator

Generate MD5, SHA-1, SHA-256, SHA-384, or SHA-512 hashes from any text input.

Compute cryptographic hashes of any UTF-8 string using the most common algorithms: MD5, SHA-1, SHA-256, SHA-384, and SHA-512. Output is a lowercase hex or base64 digest. Useful for verifying data integrity, generating checksums, and working with APIs that require signed requests.

Example input:

{
  "input": "Hello, World!",
  "algorithm": "sha256",
  "encoding": "hex"
}

JWT Decoder

Decode and verify JSON Web Tokens — header, payload, claims, and signature.

Paste a JSON Web Token to instantly decode its header and payload. Optionally supply a secret or public key to verify the signature.

Example input:

{
  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c"
}
