      com.sun.midp.crypto.RsaShaSig

RsaShaSig
final public class RsaShaSig extends Signature (Code)
Implements RSA SHA1 Signatures.


Field Summary
 RSASigrsaSig
     Common signature class.

Constructor Summary
public  RsaShaSig()
     Constructs an RSA signature object that uses SHA1 as message digest algorithm.

Method Summary
public  StringgetAlgorithm()
     Gets the signature algorithm.
public  intgetLength()
     Gets the byte-length of the signature.
public  voidinitSign(PrivateKey theKey)
     Initializes the RSASig object with the appropriate Key for signature creation.
public  voidinitVerify(PublicKey theKey)
     Initializes the RSASig object with the appropriate Key for signature verification.
public  intsign(byte[] sigBuf, int sigOff, int sigLen)
     Generates the signature of all/last input data.
public  voidupdate(byte[] inBuf, int inOff, int inLen)
     Accumulates a signature of the input data.
public  booleanverify(byte[] sigBuf, int sigOff, int sigLen)
     Verifies the signature of all/last input data against the passed in signature.

Field Detail
rsaSig
RSASig rsaSig(Code)
Common signature class.




Constructor Detail
RsaShaSig
public RsaShaSig()(Code)
Constructs an RSA signature object that uses SHA1 as message digest algorithm.
exception:
  RuntimeException - if SHA-1 is not available




Method Detail
getAlgorithm
public String getAlgorithm()(Code)
Gets the signature algorithm. the algorithmimplemented by this signature object



getLength
public int getLength()(Code)
Gets the byte-length of the signature. the byte-length of the signature produced by this object



initSign
public void initSign(PrivateKey theKey) throws InvalidKeyException(Code)
Initializes the RSASig object with the appropriate Key for signature creation.
Parameters:
  theKey - the key object to use for signing
exception:
  InvalidKeyException - if the key type is inconsistent with the mode or signature implementation.



initVerify
public void initVerify(PublicKey theKey) throws InvalidKeyException(Code)
Initializes the RSASig object with the appropriate Key for signature verification.
Parameters:
  theKey - the key object to use for verification
exception:
  InvalidKeyException - if the key type is inconsistent with the mode or signature implementation.



sign
public int sign(byte[] sigBuf, int sigOff, int sigLen) throws SignatureException(Code)
Generates the signature of all/last input data. A call to this method also resets this signature object to the state it was in when previously initialized via a call to init(). That is, the object is reset and available to sign another message.
Parameters:
  sigBuf - the output buffer to store signature data
Parameters:
  sigOff - starting offset within the output buffer at whichto begin signature data
Parameters:
  sigLen - max length the signature can be number of bytes of signature output in sigBuf
exception:
  SignatureException - if the signature algorithm does not pad the message and themessage is not block aligned



update
public void update(byte[] inBuf, int inOff, int inLen) throws SignatureException(Code)
Accumulates a signature of the input data. When this method is used, temporary storage of intermediate results is required. This method should only be used if all the input data required for the signature is not available in one byte array. The sign() or verify() method is recommended whenever possible.
Parameters:
  inBuf - the input buffer of data to be signed
Parameters:
  inOff - starting offset within the input buffer for data tobe signed
Parameters:
  inLen - the byte length of data to be signed
exception:
  SignatureException - if the signature algorithm does not pad the message and themessage is not block aligned
See Also:   RsaShaSig.verify(byte[],int,int,byte[],int,short)



verify
public boolean verify(byte[] sigBuf, int sigOff, int sigLen) throws SignatureException(Code)
Verifies the signature of all/last input data against the passed in signature. A call to this method also resets this signature object to the state it was in when previously initialized via a call to init(). That is, the object is reset and available to verify another message.
Parameters:
  sigBuf - the input buffer containing signature data
Parameters:
  sigOff - starting offset within the sigBuf where signaturedata begins
Parameters:
  sigLen - byte length of signature data true if signature verifies, false otherwise
exception:
  SignatureException - if the signature algorithm does not pad the message and themessage is not block aligned
