Question

I want to code a c program to perform ripemd160 hash on a char array. But I cannot figure out how could I do it. Can anyone suggest a c code to do the following?

What I have tried:

I came across this function in OpenSSL but I cannot figureout how to use it

unsigned char *RIPEMD160(const unsigned char *d, unsigned long n, unsigned char *md);

Solution 1

Have you considered reading the documentation: /docs/man1.0.2/man3/RIPEMD160.html[^] at all?

Damn! :-D

what does the 'unsigned long n' do in it.

RIPEMD160() computes the RIPEMD-160 message digest of the n bytes at d and places it in md (which must have space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output). If md is NULL, the digest is placed in a static array.

Reading documentation is clearly not a strong suite here ... :sigh:

Trebor make strong suites. :)

Extra strong, sometimes!

Solution 2

What about The Documentation[^]?

Looks you are unfamiliar with the documentese (you should fix that as soon as possible).

try

C

const char mystr = "My Beautiful String"; // first parameter is the input string
unsigned long len = strlen( mystr ); // 2nd parameter is the length of the input string
unsigned char myhash[20]; // 3rd parameter is the (output) hash array
RIPEMD160( (const unsigned char *)mystr, len, myhash);

can you explain to me the parameters of this function

" unsigned char *RIPEMD160(const unsigned char *d, unsigned long n,
unsigned char *md);"
