API

(cyclone base64)

[procedure] (base64-encode [[input-port] [output-port]])

Read and write encoding to default input / output ports, or specific ports if given.

[procedure] (base64-encode-string str)

Return a base64 encoded representation of string according to the official base64 standard as described in RFC3548.

[procedure] (base64-encode-bytevector bv)

Return a base64 encoded representation of bytevector according to the official base64 standard as described in RFC3548.

[procedure] (base64-decode [[input-port] [output-port]])

Read and write decoding to default input / output ports, or specific ports if given.

[procedure] (base64-decode-string str)

Return a base64 decoded representation of string, also interpreting the alternate 62 & 63 valued characters as described in RFC3548. Other out-of-band characters are silently stripped, and = signals the end of the encoded string. No errors will be raised.

Create a result buffer with the maximum possible length for the input, and pass it to the internal base64-decode-string! utility. If the resulting length used is exact, we can return that buffer, otherwise we return the appropriate substring.

[procedure] (base64-decode-bytevector bv)

Same as above but decode the given bytevector.

[procedure] (base64-encode-header encoding str . o)

Return a base64 encoded representation of the string str as per RFC1522, split across multiple MIME-header lines as needed to keep each lines length less than max-col. The string is encoded as is, and the encoding enc is just used for the prefix, i.e. you are responsible for ensuring str is already encoded according to enc. The optional argument nl is the newline separator, defaulting to crlf.

Examples

(import (scheme base) 
        (cyclone base64) 
        (cyclone string) 
        (cyclone test))
(test-group "base64"

    (test "YW55IGNhcm5hbCBwbGVhc3VyZS4="
        (base64-encode-string "any carnal pleasure."))
    (test "YW55IGNhcm5hbCBwbGVhc3VyZQ=="
        (base64-encode-string "any carnal pleasure"))
    (test "YW55IGNhcm5hbCBwbGVhc3Vy"
        (base64-encode-string "any carnal pleasur"))
    (test "YW55IGNhcm5hbCBwbGVhc3U="
        (base64-encode-string "any carnal pleasu"))
    (test "YW55IGNhcm5hbCBwbGVhcw=="
        (base64-encode-string "any carnal pleas"))

    (test "any carnal pleas"
        (base64-decode-string "YW55IGNhcm5hbCBwbGVhcw=="))
    (test "any carnal pleasu"
        (base64-decode-string "YW55IGNhcm5hbCBwbGVhc3U="))
    (test "any carnal pleasur"
        (base64-decode-string "YW55IGNhcm5hbCBwbGVhc3Vy"))
    (test "any carnal pleas"
        (base64-decode-string "YW55IGNhcm5hbCBwbGVhcw"))
    (test "any carnal pleasu"
        (base64-decode-string "YW55IGNhcm5hbCBwbGVhc3U"))
)
