int extract_user_salt | ( | const char ** | salt_begin, |
const char ** | salt_end | ||
) |
Finds the interval which envelopes the user salt in a crypt password The crypt format is assumed to be $a$bbbb$cccccc\0 and the salt is found by counting the delimiters and marking begin and end.
[in,out] | salt_begin | As input, pointer to start of crypt passwd, as output, pointer to first byte of the salt |
[in,out] | salt_end | As input, pointer to the last byte in passwd, as output, pointer to the byte immediately following the salt ($) |
void generate_user_salt | ( | char * | buffer, |
int | buffer_len | ||
) |
Generate a random string using ASCII characters but avoid separator character.
Stdlib rand and srand are used to produce pseudo random numbers between with about 7 bit worth of entropty between 1-127.

Get the integer value after rounds= where ever it occurs in the string.
if the last char after the int is a , or $ that is fine anything else is an error.
