Method Detail

encrypt

boolean encrypt(InputStream publicKeyOfRecipient,
              String inputDataName,
              InputStream plainInputData,
              OutputStream target)

encrypts the plain input data with the public key (without signing the message)

Parameters:

publicKeyOfRecipient - the public key stream of the message recipient

inputDataName - the (file)name of the input data

plainInputData - the input data stream

target - the encrypted (ascii-armored) target stream

Returns:

true if encryption is successful

encrypt

boolean encrypt(InputStream publicKeyOfRecipient,
              InputStream privateKeyOfSender,
              String userIdOfSender,
              String passwordOfSendersPrivateKey,
              String inputDataName,
              InputStream plainInputData,
              OutputStream target)

encypts the plain input data with the public key and signs it with the private key

Parameters:

publicKeyOfRecipient - the public key stream of the message recipient

privateKeyOfSender - the private key stream of the message sender

userIdOfSender - the user id of the message sender

passwordOfSendersPrivateKey - the password for the private key of the sender

inputDataName - the (file)name of the input data

plainInputData - the input data stream

target - the encrypted (ascii-armored) target stream

Returns:

true if encryption and signing successful

decrypt

              InputStream privateKeyOfReceiver,
              InputStream encryptedData,
              OutputStream target)

decrypts the encypted data stream with the recipients private key

Parameters:

passwordOfReceiversPrivateKey - the password for the receiver's private key

privateKeyOfReceiver - the receiver's private key

encryptedData - the encrypted data

target - the plain data stream

Returns:

true if decryption is successful

decrypt
