Public Methods

Method	Description
BitcoinValueToFriendlyString ( long value ) : string	Returns the given value in nanocoins as a 0.12 type string.
BitcoinValueToFriendlyString ( ulong value ) : string	Returns the given value in nanocoins as a 0.12 type string.
BytesToHexString ( byte bytes ) : string	Returns the given byte array hex encoded.
DoubleDigest ( byte input ) : byte[]	See DoubleDigest(byte[], int, int).
DoubleDigest ( byte input, int offset, int length ) : byte[]	Calculates the SHA-256 hash of the given byte range, and then hashes the resulting hash again. This is standard procedure in BitCoin. The resulting hash is in big endian form.
DoubleDigestTwoBuffers ( byte input1, int offset1, int length1, byte input2, int offset2, int length2 ) : byte[]	Calculates SHA256(SHA256(byte range 1 + byte range 2)).
ReadUint16Be ( byte bytes, int offset ) : ushort
ReadUint32 ( byte bytes, int offset ) : uint
ReadUint32Be ( byte bytes, int offset ) : uint
ReverseBytes ( byte bytes ) : byte[]	Returns a copy of the given byte array in reverse order.
Sha256Hash160 ( byte input ) : byte[]	Calculates RIPEMD160(SHA256(input)). This is used in Address calculations.
ToNanoCoins ( string coins ) : ulong	Convert an amount expressed in the way humans are used to into nanocoins. This takes string in a format understood by System.Double.Parse(string), for example "0", "1", "0.10", "1.23E3", "1234.5E-5".
ToNanoCoins ( uint coins, uint cents ) : ulong	Convert an amount expressed in the way humans are used to into nanocoins.
Uint32ToByteArrayBe ( uint val, byte @out, int offset ) : void
Uint32ToByteArrayLe ( uint val, byte @out, int offset ) : void

Private Methods

Method	Description
DecodeCompactBits ( long compact ) : BigInteger
DecodeMpi ( byte mpi ) : BigInteger	MPI encoded numbers are produced by the OpenSSL BN_bn2mpi function. They consist of a 4 byte big endian length field, followed by the stated number of bytes representing the number in big endian format.
