# Pgp Encryption Tool — REST API endpoint `pgp-encryption-tool`

Encrypt or decrypt a short message with RSA-OAEP (SHA-256) PEM keys, or generate a new RSA key pair. Returns the armoured ciphertext block, the decrypted plaintext, or the PEM public/private key pair. Note: this uses plain RSA-OAEP with SPKI/PKCS#8 PEM keys, not the OpenPGP message format. Messages are limited to the RSA block size (190 bytes for 2048-bit keys).
