The HashData function
I've written a function that hashes data all the different ways Shareaza can. I wrote it and got it working in the Shareaza 2.0 code, and then updated it to work with camper's new hashing code.
Shareaza 2.0 camper's new code
The objects that compute the hashes are the same. They are:
- CMD4
- CMD5
- CSHA
- CTigerTree
- CED2K
The places that store the hash values are not the same.
||Object|Value Size|Value (2.0)|Size (2.0)|Value (camper)|Size (camper)||CMD4|16 bytes|MD4|sizeof(MD4)|CMD4::MD4Digest|sizeof(CMD4::MD4Digest)||CMD5|16 bytes|MD5|sizeof(MD5)|Hashes::Md5Hash|Hashes::Md5Hash::byteCount||CSHA|20 bytes|SHA1|sizeof(SHA1)|Hashes::Sha1Hash|Hashes::Sha1Hash::byteCount||CTigerTree|24 bytes|TIGEROOT|sizeof(TIGEROOT)|Hashes::TigerHash|Hashes::TigerHash::byteCount||CED2K|16 bytes|MD4|sizeof(MD4)|Hashes::Ed2kHash|Hashes::Ed2kHash::byteCount||
The results of each function are pasted on the 2 pages above. Shareaza 2.0 produces all 0s for no data for tiger and donkey, while camper's new code produces hash data. The MD4 and donkey hashes are the same.
