Outils de sécurité
Passwords, passphrases, API keys, JWT decoding, checksums and anonymization.
Générateur de Strong mot de passeCrypto-random passwords with full policy control.Générateur de phrase secrèteDiceware-style memorable passphrases.Testeur de mot de passe StrengthEstimate entropy and crack-time of a password.Générateur de API KeyRandom hex / Base64 secrets of any length.Générateur de base Auth HeaderBuild and decode Authorization: Basic headers.Décodeur de JWTInspect JWT header, payload and signature metadata.Vérificateur de somme de contrôleCompare a file hash against the published digest.Scanner de SecretFind leaked API keys, tokens, private keys, JWTs and connection strings in config files, logs or code.Anonymiseur de PIIMask emails, phone numbers, SSNs, card numbers, IPs, IBANs, MACs and JWTs in logs before sharing them.Générateur de TOTP CodeGenerate RFC 6238 time-based one-time passwords from a Base32 secret, with the otpauth URI.Vérificateur de JWT signatureDecode a JWT and verify its HS256 signature locally, with exp/nbf/iat claim checks.EXIF RemoverRemove EXIF, GPS location, camera info, IPTC and comments from JPG, PNG and WebP photos in one batch — every cleaned file is re-parsed in your browser to prove zero metadata remains, and your photos are never uploaded.Générateur de JWTSign and verify JSON Web Tokens entirely in your browser — HS256, HS384, HS512, RS256 and ES256 run on your own WebCrypto, fresh RSA-2048/EC P-256 pairs export as PKCS#8 and SPKI PEM, exp/iat come back as human dates, and the unsigned "none" algorithm is refused by design. Nothing is uploaded.JWT SignerSeal a payload with RS256 (or HS256/HS384/HS512 and ES256) right in the browser: paste claims and a PKCS#8 private key — or generate an RSA/EC pair on the spot — then verify the result on the same page. "none" is never accepted, and your keys never leave this machine.To Bech32Bech32 is an encoding scheme primarily used for Bitcoin SegWit addresses (BIP-0173). It uses a 32-character alphabet that excludes easily confused characters (1, b, i, o) and includes a checksum for error detection. Bech32m (BIP-0350) is an
