Module B64

module B64: sig .. end

Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. It is specified in RFC 4648.

val default_alphabet : string

A 64-character string specifying the regular Base64 alphabet.

val uri_safe_alphabet : string

A 64-character string specifying the URI- and filename-safe Base64 alphabet.

val decode : ?alphabet:string -> string -> string

decode s decodes the string s that is encoded in base64 format. Will leave trailing NULLs on the string, padding it out to a multiple of 3 characters.

val encode : ?pad:bool -> ?alphabet:string -> string -> string

encode s encodes the string s into base64. If pad is false, no trailing padding is added.
