module Base64:sig..end
Base64 encoding as described in RFC 2045
val encode : ?pos:int ->
?len:int ->
?linelength:int ->
?crlf:bool -> ?plus:char -> ?slash:char -> string -> stringCompute the "base 64" encoding of the given string argument. Note that the result is a string that only contains the characters a-z, A-Z, 0-9, +, /, =, and optionally spaces, CR and LF characters.
If pos and/or len are passed, only the substring starting at
pos (default: 0) with length len (default: rest of the string)
is encoded.
The result is divided up into lines not longer than linelength
(without counting the line separator); default: do not divide lines.
If linelength is smaller than 4, no line division is performed.
If linelength is not divisible by 4, the produced lines are a
bit shorter than linelength.
If crlf (default: false) the lines are ended by CRLF; otherwise
they are only ended by LF.
(You need the crlf option to produce correct MIME messages.)
By default, the 63rd character of the alphabet is '+', and the
64th character is '/'. By passing plus and slash you can
choose different characters.

val decode : ?pos:int ->
?len:int ->
?accept_spaces:bool -> ?plus:char -> ?slash:char -> string -> stringDecodes the given string argument.
If pos and/or len are passed, only the substring starting at
pos (default: 0) with length len (default: rest of the string)
is decoded.
If accept_spaces (default: false) is set, the function ignores
white space contained in the string to decode (otherwise the
function fails if it finds white space). Furthermore, the character
'>' is considered as "space", too (so you don't have trouble with
mbox mailboxes that accidentally quote "From").
By default, the 63rd character of the alphabet is '+', and the
64th character is '/'. By passing plus and slash you can
choose different characters.
