base58dec: Base58 Decode

In secretbase: Cryptographic Hash, Extendable-Output and Binary/Text Encoding Functions

Base58 Decode

Description

Decodes a character string or raw vector from base58 encoding with checksum.

Usage

base58dec(x, convert = TRUE)

Arguments

x	a character string or raw vector containing base58 encoded data.
convert	logical TRUE to convert back to a character string, FALSE to convert back to a raw vector or NA to decode and then unserialize back to the original object.

Details

The 4-byte checksum suffix is verified using double SHA-256 and an error is raised if validation fails. Note: does not expect a version byte prefix (unlike Bitcoin Base58Check).

The value of convert should be set to TRUE, FALSE or NA to be the reverse of the 3 encoding operations (for strings, raw vectors and arbitrary objects), in order to return the original object.

Value

A character string, raw vector, or other object depending on the value of convert.
