Ferramentas de segurança
Passwords, passphrases, API keys, JWT decoding, checksums and anonymization.
Gerador de Strong senhaCrypto-random passwords with full policy control.Gerador de frase secretaDiceware-style memorable passphrases.Testador de senha StrengthEstimate entropy and crack-time of a password.Gerador de API KeyRandom hex / Base64 secrets of any length.Gerador de básico Auth HeaderBuild and decode Authorization: Basic headers.Decodificador de JWTInspect JWT header, payload and signature metadata.Verificador de checksumCompare 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.Ofuscador de PIIMask emails, phone numbers, SSNs, card numbers, IPs, IBANs, MACs and JWTs in logs before sharing them.Gerador de TOTP CodeGenerate RFC 6238 time-based one-time passwords from a Base32 secret, with the otpauth URI.Verificador de JWT assinaturaDecode 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.Gerador 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
