Constructor Detail

BaseRSAPublicKey

protected BaseRSAPublicKey()

Constructs an RSA private key, without setting the parameters. Subclasses should call one of the setRsaParams methods in each of their constructors.

Method Detail

getModulus

public java.math.BigInteger getModulus()

Returns the public modulus n.

Specified by:

getModulus in interface RSAKey

Returns:

the public modulus n.

getExponent

public java.math.BigInteger getExponent()

Returns the public exponent e.

Specified by:

getExponent in interface RSAKey

Returns:

the public exponent e.

getAlgorithm

public java.lang.String getAlgorithm()

Returns the name of the algorithm, for this class always "RSA".

Specified by:

getAlgorithm in interface java.security.Key

Returns:

the name of the algorithm, "RSA".

setRsaParams

protected void setRsaParams(java.math.BigInteger n,
                java.math.BigInteger e)

Sets the RSA parameters n and e.

Throws:

java.lang.NullPointerException - if n == null || e == null

toString

public java.lang.String toString()

Returns a string representation of this key.

Overrides:

toString in class java.lang.Object

Returns:

a string representation of this key.
