Encrypt sensitive text using AES-256, TripleDES, or Rabbit algorithms with your secret passkey.
Detailed analysis of password entropy, composition score, and supercomputer crack time estimates.
Generate cryptographic MD5, SHA-1, SHA-256, and SHA-512 hashes from input string.
Decode JSON Web Token headers, payload claims, and expiration date without sending it to any server.
Generate cryptographically random Version-4 UUIDs.
Generate time-based 6-digit OTP codes (RFC 6238) from your 2FA Base32 secret key.
Compute secure bcrypt hashes or verify a plain text password against a bcrypt hash string.
Cryptography is the cornerstone of modern digital security, privacy, and data integrity. Our Cryptography & Security Suite provides military-grade symmetric encryption (AES-256), cryptographic hashing (SHA-256, MD5), password strength evaluation, and identity generation — processed 100% locally inside your browser memory.
Encrypt sensitive text and secret notes with passphrases using Advanced Encryption Standard (AES) with a 256-bit key length. Decrypt ciphertext back to clear text offline.
Generate cryptographic checksums (SHA-256, SHA-512, MD5) for file integrity checks and password verification. Hashes are one-way cryptographic functions.
Analyze password strength using entropy metrics and inspect decoded JSON Web Token (JWT) header and payload data without exposing tokens to web servers.
Yes. All encryption algorithms (CryptoJS implementation) run strictly inside your browser instance. Your plain text and secret keys are never transmitted across any network connection.
No. Because we store zero data and perform zero server processing, your secret key is known only to you. If you lose your secret key, the AES encrypted ciphertext cannot be decrypted.
