• PGP Message Encryptor & Decryptor: Encrypt and decrypt text messages with password-based armored ASCII blocks and tamper detection
• Image Steganography: Conceal secret messages inside image pixels or extract hidden text.
• Hash & HMAC Calculator: Real-time text hashing for SHA-256, SHA-512, MD5, and secret-key HMACs.
• HMAC Keyed-Hash Generator: Generate and verify keyed-hash message authentication codes (HMAC-SHA256, SHA-384, SHA-512) via Web Crypto.
• Bcrypt & Password Hasher: Compute and verify standard Bcrypt and PBKDF2 password hashes with customizable cost and salt.
• Argon2 Hash Calculator & Inspector: Inspect and configure Argon2 (Argon2id, Argon2i) hashes, memory parameters, and iteration costs
• RSA Keypair Generator: Generate cryptographic RSA public and private keypairs (2048/4096-bit) in PEM format using Web Crypto
• Secure Random Key Generator: Generate cryptographically random keys for API secrets, JWT secrets, and env vars.
