Method Detail

engineGetEncoded

protected byte[] engineGetEncoded()
                           throws IOException

Returns the IV parameter spec encoded as a DER-encoded ASN.1 OCTET-STRING.

Specified by:

engineGetEncoded in class AlgorithmParametersSpi

Returns:

the IV parameter spec as a DER-ecoded OCTET-STRING

Throws:

IOException

engineGetEncoded

protected byte[] engineGetEncoded(String format)
                           throws IOException

Returns the IV parameter spec in the specified format. Supported formats are:

• ASN.1: returns the IV encoded as a DER-encoded ASN.1 OCTET-STRING
• RAW: returns the RAW IV bytes, with no encoding
• Luna: returns the IV encoded in a Luna proprietary format that is equivalent to the DER-encoded format without the initial 0x04 tag byte. This format is only used internal to the provider

Specified by:

engineGetEncoded in class AlgorithmParametersSpi

Parameters:

format - the encoding to use for the returned IV

Returns:

the IV parameter spec in the specified format

Throws:

IOException

engineGetParameterSpec

protected <T extends AlgorithmParameterSpec> T engineGetParameterSpec(Class<T> paramSpec)
                                                               throws InvalidParameterSpecException

Specified by:

engineGetParameterSpec in class AlgorithmParametersSpi

Throws:

InvalidParameterSpecException

engineInit

protected void engineInit(AlgorithmParameterSpec paramSpec)
                   throws InvalidParameterSpecException

Specified by:

engineInit in class AlgorithmParametersSpi

Throws:

InvalidParameterSpecException

engineInit

protected void engineInit(byte[] params)
                   throws IOException

Initialize the parameters with an IV given as a DER-encoded ASN.1 OCTET-STRING.

Specified by:

engineInit in class AlgorithmParametersSpi

Parameters:

params - DER-encoded IV parameter

Throws:

IOException

engineInit

protected void engineInit(byte[] params,
                          String format)
                   throws IOException

Initialize the algorithm parameters with an IV given in the specified format. Supported formats are:

• ASN.1: the IV is given as a DER-encoded ASN.1 OCTET-STRING
• RAW: the IV is given as a raw byte array with no encoding

Specified by:

engineInit in class AlgorithmParametersSpi

Parameters:

params - the encoded IV

format - the encoding used in the IV

Throws:

IOException

engineToString

protected String engineToString()

Specified by:

engineToString in class AlgorithmParametersSpi
