Hash / Token / Security Helpers
SHA-1 Generator
Computes a SHA-1 digest from text using browser cryptography and returns hexadecimal output. SHA-1 should not be used for collision-resistant security.
Hash / Token / Security Helpers
SHA-256 Generator
Hashes pasted text with SHA-256 in the browser and returns its hexadecimal digest for comparing content fingerprints.
Hash / Token / Security Helpers
SHA-512 Generator
Hashes pasted text with SHA-512 and returns the hexadecimal digest, allowing a text fingerprint to be copied or compared.
Hash / Token / Security Helpers
HMAC Generator
Computes an HMAC-SHA-256 authentication code from text and a shared secret. Supply your own secret rather than relying on the example default.
Hash / Token / Security Helpers
CRC Checksum Generator
Calculates the CRC32 checksum of pasted text and returns its numeric value for accidental-change checks; CRC is not a cryptographic hash.
Hash / Token / Security Helpers
Password Hash Generator
Derives a PBKDF2 hash from a password and supplied salt. The example salt is fixed, so this is a helper rather than a password-storage system.
Hash / Token / Security Helpers
JWT Decoder
Decodes JWT header and payload JSON and shows the signature segment. Decoding alone does not verify the signature or trust the token claims.
Hash / Token / Security Helpers
JWT Encoder Signer
Signs a JSON payload as an HS256 JWT using a supplied secret, or decodes an existing token. Replace the example secret before using any result.
Hash / Token / Security Helpers
QR Code Generator
Generates a QR code image in the browser from text or a URL.
Hash / Token / Security Helpers
JWT Inspector Upgrade
Decodes JWT header and payload, reports signature presence and interprets exp, nbf and iat claims. It does not verify the signature or authenticate a user.
