            throws QSException
Method Detail

to_bytes

public void to_bytes(byte[] data,
                     int[] offset)
Description copied from interface: QuickSerializable
Store the object in its "on the wire" form in the byte array data, starting at index offset [0], and increment offset [0] by the number of bytes written; if data == null, increment offset [0] by the number of bytes that would have been written otherwise.
Specified by:
to_bytes in interface QuickSerializable
Following copied from interface: ostore.util.QuickSerializable
Parameters:
data - The byte array to store into, or null.
offset - A single element array whose first element is the index in data to begin writing at on function entry, and which on function exit has been incremented by the number of bytes written.

type_code

public int type_code()
Description copied from interface: QuickSerializable
Returns the unique integer associated with this class in the TypeTable.
Specified by:
type_code in interface QuickSerializable
Following copied from interface: ostore.util.QuickSerializable
Returns:
an integer unique to this class

algorithm

public String algorithm()
Description copied from interface: QSCipher
The encryption/decryption algorithm. Using this and the value of QSCipher.provider(), a user of this class should be able to produce a cipher to pass to EncryptedQS.decrypt(java.security.PrivateKey, javax.crypto.Cipher) by calling Cipher.getInstance(String, String).
Specified by:
algorithm in interface QSCipher
Following copied from interface: ostore.security.QSCipher
Returns:
the name of the cipher, for instance, "RSA/ECB/PKCS#1"

provider

public String provider()
Description copied from interface: QSCipher
The cipher's provider, as used with getInstance. Using this and the value of QSCipher.algorithm(), a user of this class should be able to produce a cipher to pass to EncryptedQS.decrypt(java.security.PrivateKey, javax.crypto.Cipher) by calling Cipher.getInstance(String, String).
Specified by:
provider in interface QSCipher
Following copied from interface: ostore.security.QSCipher
Returns:
the name of the cipher provider, for instance, "CryptixCrypto"
