sodium_bin2base64Encodes a raw binary string with base64.

Descrizione

sodium_bin2base64(string $string, int $id): string

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.

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
