Encryption and signature with same rsa private key. That could cause that error as it would be noticeably larger than a valid rsa signature could be for that modulus size. The public key is used to encrypt plaintext or to verify a digital signature. This is done using the sender's decryption key, and the signature can later be verified by. Just save them and use when is needed. When we come to decrypt ciphertext c (or generate a signature) using rsa with private key (n, d), we need to calculate the modular exponentiation m = c d mod n.
