Detailed Description

Minimal standalone SHA-1 + base64 for the WebSocket Sec-WebSocket-Accept computation (RFC 6455 §4.2.2).

This removes the hard OpenSSL dependency from the proto fuzzer — the only crypto it needs is a single SHA-1 hash of a handshake nonce which has no security implications inside a fuzzer.

Base64Encode()

std::string proto_fuzzer::detail::Base64Encode ( const uint8_t * data, std::size_t len )

inline

Minimal base64 encoder.

Parameters

data	Pointer to the input bytes to encode.
len	Number of input bytes.

Returns

Base64-encoded string.

ComputeWebSocketAcceptKey()

std::string proto_fuzzer::ComputeWebSocketAcceptKey ( const std::string & key )

inline

Compute the RFC 6455 Sec-WebSocket-Accept value for a given client key.

Parameters

key	The client-supplied Sec-WebSocket-Key header value.

Returns

The base64-encoded Sec-WebSocket-Accept string.

Sha1()

std::array< uint8_t, 20 > proto_fuzzer::detail::Sha1 ( const uint8_t * data, std::size_t len )

inline

Minimal SHA-1 (FIPS 180-4) — not for security use; only for the WS accept key.

Parameters

data	Pointer to the input bytes to hash.
len	Number of input bytes.

Returns

20-byte SHA-1 digest.
