Encrypt/Decrypt Tool i !
Supports AES, DES (symmetric), RSA-OAEP (asymmetric), and MD5 digest with custom keys and key lengths.
About This Tool
The encryption tool supports AES-CBC and DES-CBC symmetric encryption as well as RSA-OAEP asymmetric encryption. Symmetric encryption uses the same key for both operations, making it suitable for bulk data. RSA asymmetric encryption uses a public key to encrypt and a private key to decrypt, ideal for small sensitive payloads. An MD5 digest function is also included. All cryptographic operations use the browser's native Web Crypto API, so keys and plaintext never leave your device.
