base64dec: Base64 Decode

In secretbase: Cryptographic Hash, Extendable-Output and Base64 Functions

Base64 Decode

Description

Decodes a character string, raw vector or other object from base64 encoding.

Usage

base64dec(x, convert = TRUE)

Arguments

x	an object.
convert	[default TRUE] 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 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’. If conversion to a character string fails, a raw vector will be returned instead (accompanied by a warning).
