Public Methods

Method	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.

ExtractPrivateKeyFromAsn1 ( byte asn1PrivKey ) : BigInteger
PublicKeyFromPrivate ( BigInteger privKey ) : byte[]	Derive the public key by doing a point multiply of G * priv.

Method Details

EcKey() public method

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.

public EcKey ( BigInteger privKey ) : System
privKey	Org.BouncyCastle.Math.BigInteger
return	System

FromAsn1() public static method

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.

public static FromAsn1 ( byte asn1PrivKey ) : EcKey
asn1PrivKey	byte
return	EcKey

GetPrivKeyBytes() public method

Returns a 32 byte array containing the private key.

public GetPrivKeyBytes ( ) : byte[]
return	byte[]

GetPrivateKeyEncoded() public method

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.

public GetPrivateKeyEncoded ( NetworkParameters @params ) : DumpedPrivateKey
@params	NetworkParameters
return	DumpedPrivateKey

Sign() public method

Calculates an ECDSA signature in DER format for the given input hash. Note that the input is expected to be 32 bytes long.

public Sign ( byte input ) : byte[]
input	byte
return	byte[]

ToAddress() public method

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).

public ToAddress ( NetworkParameters @params ) : Address
@params	NetworkParameters
return	Address

ToAsn1() public method

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.

public ToAsn1 ( ) : byte[]
return	byte[]

ToString() public method

public ToString ( ) : string
return	string

Verify() public method

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

public Verify ( byte data, byte signature ) : bool
data	byte	Hash of the data to verify.
signature	byte	ASN.1 encoded signature.
return	bool

Verify() public static method

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

public static Verify ( byte data, byte signature, byte pub ) : bool
data	byte	Hash of the data to verify.
signature	byte	ASN.1 encoded signature.
pub	byte	The public key bytes to use.
return	bool
