module Base64: BatBase64
exception Invalid_char
This exception is raised when reading an invalid character
from a base64 input.
exception Invalid_table
This exception is raised if the encoding or decoding table
size is not correct.
type char array
An encoding table maps integers 0..63 to the corresponding char.
type int array
A decoding table maps chars 0..255 to the corresponding 0..63 value
or -1 if the char is not accepted.
val str_encode : ?tbl:encoding_table -> string -> string
Encode a string into Base64.
val str_decode : ?tbl:decoding_table -> string -> string
Decode a string encoded into Base64, raise Invalid_char if a
character in the input string is not a valid one.
val encode : ?tbl:encoding_table -> 'a BatIO.output -> 'a BatIO.output
Generic base64 encoding over an output.
val decode : ?tbl:decoding_table -> BatIO.input -> BatIO.input
Generic base64 decoding over an input.
val make_decoding_table : encoding_table -> decoding_table
Create a valid decoding table from an encoding one.
