Herramientas de seguridad
Passwords, passphrases, API keys, JWT decoding, checksums and anonymization.
Generador de Strong contraseñaCrypto-random passwords with full policy control.Generador de frase de contraseñaDiceware-style memorable passphrases.Probador de contraseña StrengthEstimate entropy and crack-time of a password.Generador de API KeyRandom hex / Base64 secrets of any length.Generador de básico Auth HeaderBuild and decode Authorization: Basic headers.Decodificador de JWTInspect JWT header, payload and signature metadata.Verificador de suma de verificaciónCompare a file hash against the published digest.Escáner de SecretFind leaked API keys, tokens, private keys, JWTs and connection strings in config files, logs or code.Ofuscador de PIIMask emails, phone numbers, SSNs, card numbers, IPs, IBANs, MACs and JWTs in logs before sharing them.Generador de TOTP CodeGenerate RFC 6238 time-based one-time passwords from a Base32 secret, with the otpauth URI.Verificador de JWT firmaDecode 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.Generador 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
