使用 RSA 加密和解密示例：
// Generate a public/private key pair to use for this example. The library // also provides two utility functions (LoadPublicKey and LoadPrivateKey) // that can be used to load keys from PEM/DER-encoded data. privateKey, err := rsa.GenerateKey(rand.Reader, 2048) if err != nil { panic(err) } // Instantiate an encrypter using RSA-OAEP with AES128-GCM. An error would // indicate that the selected algorithm(s) are not currently supported. publicKey := &privateKey.PublicKey encrypter, err := NewEncrypter(RSA_OAEP, A128GCM, publicKey) if err != nil { panic(err) } // Encrypt a sample plaintext. Calling the encrypter returns an encrypted // JWE object, which can then be serialized for output afterwards. An error // would indicate a problem in an underlying cryptographic primitive. var plaintext = []byte("Lorem ipsum dolor sit amet") object, err := encrypter.Encrypt(plaintext) if err != nil { panic(err) } // Serialize the encrypted object using the full serialization format. // Alternatively you can also use the compact format here by calling // object.CompactSerialize() instead. serialized, err := object.FullSerialize() // Now let's instantiate a decrypter so we can get back the plaintext. decrypter, err := NewDecrypter(privateKey) if err != nil { panic(err) } // Parse the serialized, encrypted JWE object. An error would indicate that // the given input did not represent a valid message. object, err = Parse(serialized) if err != nil { panic(err) } // Now we can decrypt and get back our original plaintext. An error here // would indicate the the message failed to decrypt, e.g. because the auth // tag was broken and the message was tampered with. decrypted, err := decrypter.Decrypt(object) if err != nil { panic(err) } fmt.Printf(string(decrypted)) // output: Lorem ipsum dolor sit amet
