Encryption Toolkit
Encrypt and decrypt text with AES, and generate RSA key pairs — entirely in your browser using the native Web Crypto API.
How these fit together
AES Encrypt/Decrypt encrypts or decrypts text with AES-GCM or AES-CBC, deriving the key from a passphrase via PBKDF2 rather than requiring you to manage a raw key — the common case of "encrypt this text with a password" in one place, running entirely on the browser's native Web Crypto API. That covers symmetric encryption, where one key does both directions; for asymmetric encryption or signing, where a public and private key each do half the job, RSA Key Pair Generator generates a real key pair as standard PEM, for either RS256-style signing or RSA-OAEP encryption.
