Method Details

getFormat

public String getFormat()

return the encoding format we produce in getEncoded().

Specified by:

getFormat in interface Key

Overrides:

getFormat in class BCRSAPrivateKey

Returns:

the encoding format we produce in getEncoded().

getEncoded

public byte[] getEncoded()

Return a PKCS8 representation of the key. The sequence returned represents a full PrivateKeyInfo object.

Specified by:

getEncoded in interface Key

Overrides:

getEncoded in class BCRSAPrivateKey

Returns:

a PKCS8 representation of the key.

getPublicExponent

public BigInteger getPublicExponent()

return the public exponent.

Specified by:

getPublicExponent in interface RSAPrivateCrtKey

Returns:

the public exponent.

getPrimeP

public BigInteger getPrimeP()

return the prime P.

Specified by:

getPrimeP in interface RSAPrivateCrtKey

Returns:

the prime P.

getPrimeQ

public BigInteger getPrimeQ()

return the prime Q.

Specified by:

getPrimeQ in interface RSAPrivateCrtKey

Returns:

the prime Q.

getPrimeExponentP

public BigInteger getPrimeExponentP()

return the prime exponent for P.

Specified by:

getPrimeExponentP in interface RSAPrivateCrtKey

Returns:

the prime exponent for P.

getPrimeExponentQ

public BigInteger getPrimeExponentQ()

return the prime exponent for Q.

Specified by:

getPrimeExponentQ in interface RSAPrivateCrtKey

Returns:

the prime exponent for Q.

getCrtCoefficient

public BigInteger getCrtCoefficient()

return the CRT coefficient.

Specified by:

getCrtCoefficient in interface RSAPrivateCrtKey

Returns:

the CRT coefficient.

destroy

public void destroy()

Destroy this key, clearing the key material it holds.

The CRT factors and exponents are dropped along with the inherited private exponent; the (public) modulus and public exponent are retained, so hashCode() remains stable across destruction. See BCRSAPrivateKey.destroy() for the full contract.

Specified by:

destroy in interface Destroyable

Overrides:

destroy in class BCRSAPrivateKey

hashCode

public int hashCode()

Overrides:

hashCode in class BCRSAPrivateKey

equals

public boolean equals(Object o)

Overrides:

equals in class BCRSAPrivateKey

toString

public String toString()

Overrides:

toString in class BCRSAPrivateKey
