Class SigningPrivateKey
java.lang.Object
net.i2p.data.DataStructureImpl
net.i2p.data.SigningPrivateKey
- All Implemented Interfaces:
- DataStructure
public class SigningPrivateKey
- extends DataStructureImpl
Defines the SigningPrivateKey as defined by the I2P data structure spec.
A private key is 256byte Integer. The private key represents only the
exponent, not the primes, which are constant and defined in the crypto spec.
This key varies from the PrivateKey in its usage (signing, not decrypting)
