Methods

Decode(String, out Int32)

Converts an hexadecimal string to an array of bytes. If the string contains a valid checksum, checksumResult returns CEP57Checksum.ValidChecksum. If the string contains an invalid checksum, checksumResultreturns CEP57Checksum.InvalidChecksum. checkumResultreturns CEP57Checksum.NoChecksum if the string does not include CEP57 checksum.

Declaration
public static byte[] Decode(string hex, out int checksumResult)
Parameters
Type Name Description
System.String hex
System.Int32 checksumResult
Returns
Type Description
System.Byte[]

Encode(Byte[])

Encodes an array of bytes into an hexadecimal string with CEP57 checksum. Arrays longer than 75 bytes do not include the checksum.

Declaration
public static string Encode(byte[] input)
Parameters
Type Name Description
System.Byte[] input
Returns
Type Description
System.String

HasChecksum(String)

Returns true if the input hexadecimal string includes the CEP57 checksum. An string includes checksum when letters are mixed-cased.

Declaration
public static bool HasChecksum(string hex)
Parameters
Type Name Description
System.String hex
Returns
Type Description
System.Boolean
