				) pure nothrow @safe;

Parameters

Name	Description
sourceLength	The length of the Base64 encoding.

Returns

The length of the decoded string corresponding to a Base64 encoding of length sourceLength.

Example

auto encoded = "Gis8TV1u";

// Allocate a sufficiently large buffer to hold to decoded result.
auto buffer = new ubyte[Base64.decodeLength(encoded.length)];

Base64.decode(encoded, buffer);
