Security & Crypto
6 security and cryptography tools for developers. Debug and verify JWT tokens, generate MD5/SHA hashes, create cryptographically secure passwords, generate SSH key pairs, encrypt and decrypt text with AES/DES/RC4, and calculate file checksums. All cryptographic operations run entirely in your browser — your data never leaves your device.
JWT
Encode, decode, and verify JSON Web Tokens (JWT). Supports HS256, RS256, ES256, PS256 and more algorithms.
Text Hashing
Generate MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA3, and RIPEMD-160 hashes with HMAC support.
Password Generator
Generate cryptographically secure passwords and check password strength instantly. Customizable options with real-time analysis.
SSH Key Generator
Generate SSH key pairs (RSA, Ed25519) entirely in your browser. Supports passphrase encryption, fingerprint display, and public key inspection.
Text Encrypt/Decrypt
Encrypt and decrypt text using AES, DES, Triple DES, Rabbit, RC4, and RC4Drop with configurable block modes.
File Checksum
Calculate MD5, SHA-1, SHA-256, and SHA-512 checksums for any file. Supports unlimited file size.
