Encryption & Decryption
AES, RSA, and symmetric/asymmetric encryption tools
AES Encrypt
Encrypt text with AES-256-GCM, AES-CBC, AES-CTR, or AES-ECB in your browser. PBKDF2 key derivation, random IV, zero uploads.
AES Decrypt
Decrypt AES ciphertext in your browser. Supports GCM, CBC, CTR, and ECB modes with 128/192/256-bit keys. Password never transmitted.
RSA Encrypt
Encrypt text with RSA-OAEP using a public key in your browser. Generate RSA-2048 or RSA-4096 key pairs. Max ~190 bytes plaintext. Nothing uploaded.
RSA Decrypt
Decrypt RSA-OAEP ciphertext with your PEM private key in the browser. Supports RSA-2048 and RSA-4096. Private key never transmitted.
Encrypt and decrypt your sensitive data using industry-standard cryptographic algorithms. Generate and manage encryption keys, encrypt files and text with AES, RSA, and other symmetric/asymmetric methods. All encryption and decryption happens entirely in your browser — your data never touches a server, ensuring complete privacy and security.
