Công cụ bảo mật
Passwords, passphrases, API keys, JWT decoding, checksums and anonymization.
Bộ tạo Strong mật khẩuCrypto-random passwords with full policy control.Bộ tạo cụm mật khẩuDiceware-style memorable passphrases.Bộ thử mật khẩu StrengthEstimate entropy and crack-time of a password.Bộ tạo API KeyRandom hex / Base64 secrets of any length.Bộ tạo bảng Auth HeaderBuild and decode Authorization: Basic headers.Bộ giải mã JWTInspect JWT header, payload and signature metadata.Bộ xác minh truy vấnCompare a file hash against the published digest.Bộ quét SecretFind leaked API keys, tokens, private keys, JWTs and connection strings in config files, logs or code.Bộ ẩn danh PIIMask emails, phone numbers, SSNs, card numbers, IPs, IBANs, MACs and JWTs in logs before sharing them.Bộ tạo TOTP CodeGenerate RFC 6238 time-based one-time passwords from a Base32 secret, with the otpauth URI.Bộ xác minh JWT claimDecode 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.Bộ tạo 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
