Method Detail

decrypt

public byte[] decrypt(byte[] abyEncryptedData,
                      byte[] abyEncryptionData)
               throws ID3CryptException

Description copied from interface: ICryptoAgent

Decrypt an array of bytes.

Specified by:

decrypt in interface ICryptoAgent

Parameters:

abyEncryptedData - an array of encrypted bytes

abyEncryptionData - an array of bytes which are used to decrypt the encrypted data

Returns:

an array of unencrypted bytes

Throws:

ID3CryptException

encrypt

public byte[] encrypt(byte[] abyRawData,
                      byte[] abyEncryptionData)
               throws ID3CryptException

Description copied from interface: ICryptoAgent

Encrypt an array of bytes.

Specified by:

encrypt in interface ICryptoAgent

Parameters:

abyRawData - an array of bytes which are to be encrypted

abyEncryptionData - an array of bytes which are used to encrypt the raw data

Returns:

an array of encrypted bytes

Throws:

ID3CryptException

getOwnerIdentifier

public java.lang.String getOwnerIdentifier()

Description copied from interface: ICryptoAgent

Get the owner identifier for this encryption method. Each encrypted frame in a tag has its encryption method represented by a unique owner identifier. This value much match the owner identifier of a crypto agent to be used for decryption.

Specified by:

getOwnerIdentifier in interface ICryptoAgent

Returns:

a string containing the owner identifier
