RSA Encryption & Decryption
Encrypt small plaintext values with a public RSA key and decrypt Base64 ciphertext with the matching private key.
For normal RSA encryption, use the public key to encrypt and the matching private key to decrypt. The selected padding algorithm must match on both sides.

How to use RSA
- Enter or paste your input into the RSA workspace.
- Choose any available options, then run the operation or view the live result.
- Review the output, then copy or download it when that option is available.
Tip: Check your output before using it in production. Available actions and file handling differ by tool.
