Method Detail |
public static EncryptedValue encrypt(ASN1Object obj, SymmetricKey encrKey, PublicKey recipKey) throws AlgorithmIdentifierException, CipherException, InvalidKeyException
EncryptedValue
instance whose value is the DER encoding of the given ASN1Object
.
For example, to encrypt a certificate:
// The certificate to be encrypted.
X509 cert = ... ;
// The public key of the recipient.
PublicKey pubKey = ... ;
// Generate a random triple-DES encryption key.
SymmetricKeyGenerator keyGen =
SymmetricKeyGenerator.getInstance(AlgID.DES_EDE3_CBC);
SymmetricKey symmKey = keyGen.generateKey();
// Create the EncryptedValue.
EncryptedValue encCert = EncryptedValue.encrypt(cert, symmKey, pubKey);
obj
- The ASN1Object
to be encrypted.encrKey
- The symmetric key that will be used to encrypt the object. Must have a valid algorithm identifer.recipKey
- The public key that will be used to encrypt the symmetric key for the recipient.AlgorithmIdentifierException
CipherException
InvalidKeyException
public static byte[] decrypt(EncryptedValue encVal, PrivateKey recipKey) throws AlgorithmIdentifierException, CipherException, InvalidKeyException
EncryptedValue
and return the bytes of the value.
For example, to decrypt an EncryptedValue
containing a certificate:
// The EncryptedValue.
EncryptedValue encVal = ... ;
// The recipient's private key.
PrivateKey privKey = ... ;
// Decrypt and construct the resulting certificate from
// its DER encoding.
byte[] val = EncryptedValue.decrypt(encVal, privKey);
X509 cert = new X509(val);
encVal
- The EncryptedValue
to be decrypted.recipKey
- The private key of the recipient, corresponding to the public key used by the sender to encrypt.AlgorithmIdentifierException
CipherException
