public class RC2CBCParameter

extends DERSequencePr

RC2CBCParameter is parameter used in Content Encryption Algorithm Identifier in CMS object for encrypted message, for RC2_CBC algorithms. Parameter for this algorithm is made from initialization vector and key length in bits.

RC2CBCParameter ::= SEQUENCE {

rc2ParameterVersion INTEGER,

iv OCTET STRING }

rc2ParameterVersion ::= INTEGER

IV ::= OCTET STRING -- exactly 8 octets

Constructor Summary

RC2CBCParameter(int lenKey0, byte[] iv0)
Constructor takes key length in bits and IV (Initialization Vector) as byte array

Constructor Detail

RC2CBCParameter

public RC2CBCParameter(int lenKey0,
                       byte[] iv0)
                throws SMIMEException

Constructor takes key length in bits and IV (Initialization Vector) as byte array

Parameters:

lenKey0 - key length

iv0 - Initialization Vector

Throws:

SMIMEException - if Initialization Vector - IV is not 8 bytes long or key size is not 40, 64 or 128. Also, exception could be thrown in super class constructor or in super class addContent method.
