Generate random hex, base64, or alphanumeric tokens

Hash text with MD5, SHA-1, SHA-256, or SHA-512

Hash and verify passwords with bcrypt

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!).

Generate sortable ULID identifiers

AES-GCM encrypt and decrypt text with a password

Generate BIP39 mnemonic passphrases

Generate HMAC signatures with SHA-256 or SHA-512

Generate RSA-OAEP key pairs (PEM / JWK)

Analyse password strength and entropy

Detect digital signature markers in PDF files

Compute SHA-256 hash of text

Compute SHA-512 hash of text
