The ANSRPC class

Description

This class definition is employed to cast the JSON-objects returned by API-calls to bitcoind.

Slots

rpcname

character the name of the API.

result

ANY the output/result of the API.

Base 58 binary-to-text-decoding

Description

This is a modified binary-to-text decoding used for decoding Bitcoin addresses, aka Base58Check. If this is applied to a WIF address and the first and last four bytes are dropped, the result is the corresponding private key.

Usage

base58CheckDecode(x)

Arguments

x

character, string in hex format.

Value

list, the decoded elements of the string.

Base 58 binary-to-text-encoding

Description

This is a modified binary-to-text encoding used for encoding Bitcoin addresses, aka Base58Check. If this is applied to an extended private key with its trailing check sum, then the result is the Wallet Import Format, (WIF).

Usage

x

character, string in hex format.

Value

character, the encoded string.
