Méthodes publiques

Méthode Description
EcKey ( BigInteger privKey ) : System

Creates an ECKey given only the private key. This works because EC public keys are derivable from their private keys by doing a multiply with the generator value.
FromAsn1 ( byte asn1PrivKey ) : EcKey

Construct an ECKey from an ASN.1 encoded private key. These are produced by OpenSSL and stored by the BitCoin reference implementation in its wallet.
GetPrivKeyBytes ( ) : byte[]

Returns a 32 byte array containing the private key.
GetPrivateKeyEncoded ( NetworkParameters @params ) : DumpedPrivateKey

Exports the private key in the form used by the Satoshi client "dumpprivkey" and "importprivkey" commands. Use the DumpedPrivateKey.ToString method to get the string.
Sign ( byte input ) : byte[]

Calculates an ECDSA signature in DER format for the given input hash. Note that the input is expected to be 32 bytes long.
ToAddress ( NetworkParameters @params ) : Address

Returns the address that corresponds to the public part of this ECKey. Note that an address is derived from the RIPEMD-160 hash of the public key and is not the public key itself (which is too large to be convenient).
ToAsn1 ( ) : byte[]

Output this ECKey as an ASN.1 encoded private key, as understood by OpenSSL or used by the BitCoin reference implementation in its wallet storage format.
ToString ( ) : string
Verify ( byte data, byte signature ) : bool

Verifies the given ASN.1 encoded ECDSA signature against a hash using the public key.
Verify ( byte data, byte signature, byte pub ) : bool

Verifies the given ASN.1 encoded ECDSA signature against a hash using the public key.

Private Methods

Méthode Description
EcKey ( ) : System
ExtractPrivateKeyFromAsn1 ( byte asn1PrivKey ) : BigInteger
PublicKeyFromPrivate ( BigInteger privKey ) : byte[]

Derive the public key by doing a point multiply of G * priv.

Method Details
