Passwords, passphrases, API keys, JWT decoding, checksums and anonymization.
Strong 비밀번호 생성기Crypto-random passwords with full policy control.암호 문구 생성기Diceware-style memorable passphrases.비밀번호 Strength 테스터Estimate entropy and crack-time of a password.API Key 생성기Random hex / Base64 secrets of any length.기본 Auth Header 생성기Build and decode Authorization: Basic headers.JWT 디코더Inspect JWT header, payload and signature metadata.체크섬 검증기Compare a file hash against the published digest.Secret 스캐너Find leaked API keys, tokens, private keys, JWTs and connection strings in config files, logs or code.PII 마스킹Mask emails, phone numbers, SSNs, card numbers, IPs, IBANs, MACs and JWTs in logs before sharing them.TOTP Code 생성기Generate RFC 6238 time-based one-time passwords from a Base32 secret, with the otpauth URI.JWT 서명 검증기Decode 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.JWT 생성기Sign 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
