sodium_bin2base64
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
- string
-
Raw binary string.
- id
-
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.
Return Values
Base64-encoded string.
