Anatol Belski	20501c72c8	hash: Implement secret support for xxh3 and xxh128 ... A secret can be passed through the options array. The length is currently in the range of 136 to 256 bytes. The concerned algos are already marked as non serializable. Signed-off-by: Anatol Belski <ab@php.net>	2021-02-20 23:26:59 +01:00
Nikita Popov	e8a0ae186f	Fix memsize check for xxh32 ... Copy-paste mistake: The memsize limit for xxh32 should be 16, rather than 32 (which is correct for xxh64). Probably fixes oss-fuzz #29661.	2021-01-18 10:35:01 +01:00
Nikita Popov	cebdad4b53	Protect against buffer overflow in xxhash unserialization ... We need to make sure that memsize is < 32 bytes. Fixes oss-fuzz #29538.	2021-01-15 17:29:33 +01:00
Anatol Belski	23590f7c53	hash: Implement xxHash ... The implementation bundles the xxHash v0.8.0 release and includes all the variants - xxh32, 32-bit wide - xxh64, 64-bit wide - xxh3, 64-bit wide - xxh128, 128-bit wide An initial hash state can be passed through the options arrray. An additional functionality not targeted in this implementation is the secret support in xxh3 and xxh128. That can be added at a later point. The serialization for xxh3 and xxh128 should not be implemented, as the state would contain the secret. Despite the xxHash is a non crypto algorithm, the secret would be serialized as plain text which would be insecure. Closes GH-6524 Signed-off-by: Anatol Belski <ab@php.net>	2021-01-09 19:35:32 +01:00
