Description copied from interface: RSAPrivateCrtKey

Sets the value of the P parameter. The plain text data format is big-endian and right-aligned (the least significant bit is the least significant bit of last byte). Input P parameter data is copied into the internal representation.

Specified by:: setP in interface RSAPrivateCrtKey

Parameters:

buffer - the input buffer

offset - the offset into the input buffer at which the parameter value begins

length - the length of the parameter

Throws:

CryptoException - with the following reason code:

CryptoException.ILLEGAL_VALUE if the input parameter data length is inconsistent with the implementation or if input data decryption is required and fails.

clearKey

public void clearKey()

Description copied from interface: Key

Clears the key and sets its initialized state to false.

Specified by:: clearKey in interface Key
Overrides:: clearKey in class RSAKeyImpl

isInitialized

public boolean isInitialized()

Description copied from interface: Key

Reports the initialized state of the key. Keys must be initialized before being used.

A Key object sets its initialized state to true only when all the associated Key object parameters have been set at least once since the time the initialized state was set to false.

A newly created Key object sets its initialized state to false. Invocation of the clearKey() method sets the initialized state to false. A key with transient key data sets its initialized state to false on the associated clear events.

Specified by:: isInitialized in interface Key
Overrides:: isInitialized in class RSAKeyImpl

Returns:: true if the key has been initialized

getParameters

public org.bouncycastle.crypto.CipherParameters getParameters()

Description copied from class: RSAKeyImpl

Get RSAKeyParameters
