RSA is an asymmetric algorithm using two linked keys (public and private).
Usually, you encrypt with the public key and decrypt with the private key.
Maximum data size for RSA depends on the key size (e.g., 2048-bit fits ~245 bytes).
PEM format starts with -----BEGIN PUBLIC KEY----- and ends with -----END PUBLIC KEY-----.
