Text Encryption / Decryption

Encrypt and decrypt text using AES-256, RSA, or other ciphers with password-based key derivation.

Uses AES-256-GCM encryption with PBKDF2 key derivation (100,000 iterations, SHA-256). All processing happens locally in your browser using the Web Crypto API. No data is sent to any server. The output format includes salt and IV for self-contained decryption.
