public class RSAPublicKey
extends JSafeKey
implements PublicKey, RSAKey
Holds a public RSA key, for example a public key found in an X.509 certificate. This represents internal key structure in a way that facilitates its active use.

Constructor Index

o RSAPublicKey()
Default constructor.

Method Index

o decode(InputStream)
o encode(OutputStream)
There's a package-visible version of this so we can have package-private key storage.
o getExponent()
Return the RSA public exponent, as a big-endian byte array without a leading zero.
o getModulus()
Return the RSA public modulus, as a big-endian byte array without a leading zero.
o getModulusLen()
Returns the modulus length, in bits.
o init()
Called to ensure that the BSAFE key object has been created.
o isSigningOnly()
Returns true iff this key may only be used for digital signature applications.
o makeKey(byte[], byte[])
o parseKeyBits()
Parses exponent and modulus parameters from the key bits.
o toString()

Constructors

o RSAPublicKey 
  public RSAPublicKey()
Default constructor. The key must be initialized, for example by calling decode(), after construction.

Methods

o getModulus 
  public byte[] getModulus()
Return the RSA public modulus, as a big-endian byte array without a leading zero.
o getExponent 
  public byte[] getExponent()
Return the RSA public exponent, as a big-endian byte array without a leading zero.
o parseKeyBits 
  protected void parseKeyBits() throws IOException
Parses exponent and modulus parameters from the key bits.
Overrides:
parseKeyBits in class X509Key
o getModulusLen 
  public int getModulusLen()
Returns the modulus length, in bits. RSA encryption and signing produce blocks of data of this size.
o isSigningOnly 
  public boolean isSigningOnly()
Returns true iff this key may only be used for digital signature applications.
o init 
  public synchronized void init() throws InvalidKeyException
Called to ensure that the BSAFE key object has been created.
Overrides:
init in class JSafeKey
o makeKey 
  public static RSAPublicKey makeKey(byte modulus[],
                                     byte exponent[]) throws IOException
o toString 
  public String toString()
Overrides:
toString in class X509Key
o encode 
  public void encode(OutputStream out) throws InvalidKeyException, IOException
There's a package-visible version of this so we can have package-private key storage.
Overrides:
encode in class JSafeKey
o decode 
  public void decode(InputStream in) throws InvalidKeyException
Overrides:
decode in class X509Key
