Crypto and hashing

Local tools for hashes, checksums, encryption, tokens, and secure identifiers.

Crypto and hashing

MD5 hashCompute an MD5 digest for text locally in the browser

SHA-1 hashCompute a SHA-1 digest with the browser Web Crypto API

SHA-256 hashCompute a SHA-256 hash for text in the browser

SHA-512 hashCompute a SHA-512 digest with the browser Web Crypto API

SHA-3 hashCompute a FIPS 202 SHA-3 digest locally

RIPEMD-160 hashCompute a RIPEMD-160 digest locally in the browser

File hashCompute a SHA-1, SHA-256, or SHA-512 hash for a local file

CRC32 checksumCompute a CRC32 checksum to detect transfer or storage errors

Adler-32 checksumCompute an Adler-32 checksum for quick data-error detection

HMAC signerCompute a keyed HMAC for UTF-8 text.

AES encrypt and decryptEncrypt UTF-8 text with password-derived AES-256-GCM, or decrypt this tool’s envelope.

DES/3DES encrypt and decryptInspect legacy DES and two- or three-key 3DES encryption/decryption.

RSA encrypt and decryptGenerate a 2048-bit RSA-OAEP keypair and encrypt/decrypt short UTF-8 messages with SHA-256.

JWT decoder and signature verifierDecode JWT JSON and verify RS256, PS256 or ES256 signatures locally with a supplied public key; inspect claim checks separately.

PBKDF2 password hashGenerate and verify a salted PBKDF2-SHA256 password hash.

Random password generatorGenerate a random password from selected character groups.

UUID generatorGenerate secure UUID v4 or v7 batches and inspect UUID format, variant, version and supported timestamps locally.

NanoID generatorGenerate short random IDs from a configurable alphabet.

API key generatorGenerate random token strings with an optional prefix.

TOTP code generatorCalculate time-based one-time codes from a Base32 secret.

SSL certificate and PEM bundle parserInspect local PEM bundles or a DER certificate: subjects, issuers, validity, public keys, fingerprints and candidate chain order.
