Constructor Detail

RSAPrivKey

public RSAPrivKey()

Construct an empty RSAPrivKey.

RSAPrivKey

public RSAPrivKey(java.math.BigInteger modulus,
                  java.math.BigInteger privateExponent)

Method Detail

getModulus

public java.math.BigInteger getModulus()

Return the modulus.

Specified by:

getModulus in interface java.security.interfaces.RSAPrivateKey

Returns:

the modulus.

getPrivateExponent

public java.math.BigInteger getPrivateExponent()

Return the private exponent

Specified by:

getPrivateExponent in interface java.security.interfaces.RSAPrivateKey

Returns:

the private exponent.

getAlgorithm

public java.lang.String getAlgorithm()

Return the algorithm for this key.

Returns:

the string RSA.

getFormat

public java.lang.String getFormat()

Return the format this key is in. This returns "ABA" which indicates the encoded key is the form of a byte array whose contents form the string "modulus.exponent" (ie the String returned from the toString() method. This format is compatible with the AsciiEncodedKeySpec.

getEncoded

public byte[] getEncoded()

Return an encoded representation for this key. Returns a byte array that forms the string "modulus.exponent".

getFormat(), toString()

toString

public java.lang.String toString()

Generate a String representation of this key.

Returns:

The key as a string.

Overrides:

toString in class java.lang.Object
