Module structural 

Structural encoding strategies (null byte, overlong UTF-8, chunked, HPP). Structural encoding strategies — byte-level and framing manipulations.

Structs

ChunkedBody

Result of chunked transfer-encoding split.

Functions

base64_encode

Base64 encoding — standard alphabet.

base64_url_encode

Base64 URL-safe encoding — -_ alphabet, no padding.

chunked_split

Chunked transfer-encoding split — break payload across HTTP chunks.

deflate_encode

Deflate compression.

gzip_encode

Gzip compression.

hex_encode

Hex encoding.

null_byte_inject

Null byte injection — append %00 to truncate strings in C-style parsers.

overlong_utf8

Overlong UTF-8 encoding (2-byte) — represent ASCII non-alphanumeric as 2-byte sequences.

overlong_utf8_more

Extended overlong UTF-8 encoding (3-byte) — broader coverage with 3-byte sequences.

parameter_pollute

HTTP parameter pollution — duplicate parameter with a benign first value.

utf7_decode

Decode UTF-7 (RFC 2152) — the inverse of utf7_encode, i.e. exactly what a UTF-7-honoring backend computes. + opens a shift sequence of modified-Base64 carrying UTF-16BE code units, terminated by - (absorbed) or any non-Base64 byte (kept); +- is a literal +; every other byte passes through. Returns None on malformed Base64, an odd UTF-16 byte count, or unpaired surrogates — so a caller proving round-trip soundness treats undecodable input as “not recoverable” rather than guess.

utf7_encode

UTF-7 encoding per RFC 2152.
