Method Detail

encrypt

public byte[] encrypt(byte[] iv,
                      byte[] plaintext,
                      byte[] associatedData)
               throws java.security.GeneralSecurityException

Encrypts plaintext with iv and associatedData.

Throws:

java.security.GeneralSecurityException

encrypt

public byte[] encrypt(byte[] iv,
                      byte[] plaintext,
                      int ciphertextOffset,
                      byte[] associatedData)
               throws java.security.GeneralSecurityException

Encrypts plaintext with iv and associatedData.

The ciphertextOffset is the offset at which the ciphertext should start in the returned byte array.

Throws:

java.security.GeneralSecurityException

decrypt

public byte[] decrypt(byte[] iv,
                      byte[] ciphertext,
                      byte[] associatedData)
               throws java.security.GeneralSecurityException

Decrypts ciphertext with iv and associatedData.

Throws:

java.security.GeneralSecurityException

decrypt

public byte[] decrypt(byte[] iv,
                      byte[] ciphertextWithPrefix,
                      int ciphertextOffset,
                      byte[] associatedData)
               throws java.security.GeneralSecurityException

Decrypts ciphertextWithPrefix with iv and associatedData.

The ciphertextOffset is the offset at which the ciphertext starts within ciphertextWithPrefix.

Throws:

java.security.GeneralSecurityException
