bin: The data you wish to encode
id: The variant of encoding to use, which can be one of the following constants. You'll need to reuse this value when decoding with sodium_base642bin.
SODIUM_BASE64_VARIANT_ORIGINAL = 1
SODIUM_BASE64_VARIANT_ORIGINAL_NO_PADDING = 3
SODIUM_BASE64_VARIANT_URLSAFE = 5
SODIUM_BASE64_VARIANT_URLSAFE_NO_PADDING = 7
sodium_bin2base64
(PHP 7 >= 7.2.0, PHP 8)
sodium_bin2base64 — Encodes a raw binary string with base64.
Description
Converts a raw binary string into a base64-encoded string. Unlike base64_encode(), sodium_bin2base64() 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.
Parameters
