Base64 codec.
8-bit characters are encoded into 6-bit ones using ASCII lookup tables. Default tables maps 0..63 values on characters A-Z, a-z, 0-9, '+' and '/' (in that order).
This exception is raised when reading an invalid character from a base64 input.
This exception is raised if the encoding or decoding table size is not correct.
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 -> ExtBytes.Bytes.terroneous interface, kept for compatibility use encode_string instead
val str_decode : ?tbl:decoding_table -> ExtBytes.Bytes.t -> stringerroneous interface, kept for compatibility use decode_string instead
val encode_string : ?tbl:encoding_table -> string -> stringEncode a string into Base64.
val decode_string : ?tbl:decoding_table -> string -> stringDecode 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 IO.output -> 'a IO.outputGeneric base64 encoding over an output.
val decode : ?tbl:decoding_table -> IO.input -> IO.inputGeneric base64 decoding over an input.
val make_decoding_table : encoding_table -> decoding_tableCreate a valid decoding table from an encoding one.
