clojure.data.codec.base64 — org.clojure/data.codec 0.1.1

Functions for working with base64 encodings.

dec-length clj

(dec-length in-length pad-length)

Calculates what would be the length after decoding of an input array of length in-length with the specified padding length.

decode clj

(decode input)

(decode input offset length)

Returns a base64 decoded byte array.

Note: length must be a multiple of 4.

decode! clj

(decode! input offset length output)

Reads from the input byte array for the specified length starting at the offset index, and base64 decodes into the output array starting at index 0. Returns the length written to output.

Note: length must be a multiple of 4.

decoding-transfer clj

(decoding-transfer input-stream output-stream & opts)

Base64 decodes from input-stream to output-stream. Returns nil or throws IOException.

Options are key/value pairs and may be one of :buffer-size read buffer size to use, must be a multiple of 4; default is 8192.

enc-length clj

(enc-length n)

Calculates what would be the length after encoding of an input array of length n.

encode clj

(encode input)

(encode input offset length)

Returns a base64 encoded byte array.

encode! clj

(encode! input offset length output)

Reads from the input byte array for the specified length starting at the offset index, and base64 encodes into the output array starting at index 0. Returns the length written to output.

Note: if using partial input, length must be a multiple of 3 to avoid padding.

encoding-transfer clj

(encoding-transfer input-stream output-stream & opts)

Base64 encodes from input-stream to output-stream. Returns nil or throws IOException.

Options are key/value pairs and may be one of :buffer-size read buffer size to use, must be a multiple of 3; default is 6144.

pad-length clj

(pad-length input offset length)

Returns the length of padding on the end of the input array.
