Crypto Tools
Cryptography, hashing, key generation, and token generation tools running securely in your browser.
PDF signature checker
Verify the signatures of a PDF file. A signed PDF file contains one or more signatures that may be used to determine whether the contents of the file have been altered since the file was signed.
ULID generator
Generate random Universally Unique Lexicographically Sortable Identifier (ULID).
Password strength analyser
Discover the strength of your password with this client-side-only password strength analyser and crack time estimation tool.
RSA key pair generator
Generate a new random RSA private and public pem certificate key pair.
Bcrypt
Hash and compare text string using bcrypt. Bcrypt is a password-hashing function based on the Blowfish cipher.
BIP39 passphrase generator
Generate a BIP39 passphrase from an existing or random mnemonic, or get the mnemonic from the passphrase.
Encrypt / decrypt text
Encrypt clear text and decrypt ciphertext using crypto algorithms like AES, TripleDES, Rabbit or RC4.
Hash text
Hash a text string using the function you need : MD5, SHA1, SHA256, SHA224, SHA512, SHA384, SHA3 or RIPEMD160
Hmac generator
Computes a hash-based message authentication code (HMAC) using a secret key and your favorite hashing function.
Token generator
Generate random string with the chars you want, uppercase or lowercase letters, numbers and/or symbols.
UUIDs generator
A Universally Unique Identifier (UUID) is a 128-bit number used to identify information in computer systems. The number of possible UUIDs is 16^32, which is 2^128 or about 3.4x10^38 (which is a lot!).
