sodium_base642bin
Converts a base64 encoded string into raw binary. Unlike base64_decode, sodium_base642bin is constant-time (a property that is important for any code that touches cryptographic inputs, such as plaintexts or keys) and supports multiple character sets.

SODIUM_BASE64_VARIANT_URLSAFE for URL-safe (A-Za-z0-9\-_) Base64 encoding. SODIUM_BASE64_VARIANT_URLSAFE_NO_PADDING for URL-safe (A-Za-z0-9\-_) Base64 encoding, without = padding characters.
