sodium_bin2base64 — Encodes a raw binary string with base64.
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.
stringRaw binary string.

SODIUM_BASE64_VARIANT_ORIGINAL for standard (A-Za-z0-9/\+)
Base64 encoding.
SODIUM_BASE64_VARIANT_ORIGINAL_NO_PADDING for standard (A-Za-z0-9/\+)
Base64 encoding, without = padding characters.
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.
Base64-encoded string.
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.
