Thanks Marius and others.
I'm trying to implement SRP protocol by pure python.
But something wrong in my python codes, I know.
I have found RemotePassword::getUserHash() return different value with
getUserHash() in srp.py.
https://github.com/nakagami/pyfirebirdsql/blob/master/firebirdsql/srp.py#L143
For example ...
[Modified source:firebird/src/auth/SecureRemotePassword/srp.cpp]
BigInteger RemotePassword::getUserHash(const char* account, const char*
salt, const char* password)
{
hash.reset();
hash.process(account);
hash.process(":");
hash.process(password);
UCharBuffer hash1;
hash.getHash(hash1);
dumpIt("getUserHash() account", account);
dumpIt("getUserHash() salt", salt);
dumpIt("getUserHash() password", password);
dumpIt("getUserHash() hash1", hash1);
hash.reset();
hash.process(salt);
hash.process(hash1);
UCharBuffer hash2;
hash.getHash(hash2);
dumpIt("getUserHash() hash2", hash2);
BigInteger rc;
hash.getInt(rc);
dumpIt("getUserHash() rc", rc);
return rc;
}
[Result]
getUserHash() account: 'SYSDBA'
getUserHash() salt:
'2E268803000000079A478A700000002D1A6979000000026E1601C000000054F'
getUserHash() password: 'masterkey'
getUserHash() hash1
e3 95 79 9c 56 52 aa a4 53 62 73 a2 0a a7 40 e2 46 83 5c c4
getUserHash() hash2
98 0c 1c 90 a1 be 65 5f 31 09 3f 56 a9 ef 5c e7 c0 4b 26 2f
getUserHash() rc: '4DD084A42814499F781537C24753291235DE797C'
I think rc seems to be
980c1c90a1be655f31093f56a9ef5ce7c04b262f(868036694467267200852895567621828944633719891503L)
But it is '4DD084A42814499F781537C24753291235DE797C' (equal to
0x4DD084A42814499F781537C24753291235DE797C ?)
I don't realize how to convert from hash2 to rc.
Please let me know the algorithm
Best regards
