jabber_challange_digest()

Return base16 encoded hash for SASL MD5 CHALLANGE

Do zrobienia:
MD5Update() on NULL params will fail. XXX, no idea what to do.
Zwraca:
static buffer with 32 digit BASE16 HASH + NUL char
char* jabber_dcc_digest ( char *  sid,
char *  initiator,
char *  target 
)

[XXX] SOME TIME AGO, I had idea to connect jabber_dcc_digest() and jabber_digest() with one function, and use va_list for it... i don't know. jabber_dcc_digest()

Return SHA1 hash for SOCKS5 Bytestreams connections [DCC]
Make SHA1Update()'s on (uid, initiator and target)

Do zrobienia:
SHA1Update() on NULL params will fail. XXX, no idea what to do.
Do zrobienia:
We don't reencode params here to utf-8.
Zwraca:
static buffer, with 40 digit SHA1 hash + NUL char
char* jabber_digest ( const char *  sid,
const char *  password,
int  istlen 
)

jabber_digest()

Return SHA1 hash for jabber:iq:auth
Make SHA1Update()'s on recoded to utf-8 (sid and password)

Do zrobienia:
SHA1Update() on NULL params will fail. XXX, no idea what to do.
Zwraca:
static buffer, with 40 digit SHA1 hash + NUL char
char* jabber_sha1_generic ( char *  buf,
int  len 
)
static void Transform ( uint32_t  state[5],
