RIPE online MD160 Hash Generator

I've been looking for standalone header-only sha256 and ripemd160 hash functions, preferably MIT licence, but GPL and others are fine too.

I found pico256, header only, I can integrate into a project. But I can't find both hash functions I need. I am not sure if I can just rip the bits out I want from OpenSSL, it's too big and complex.

If I can find a reasonable description of sha256 and ripemd160, I might have a go at implementing them myself.

Until then, does anyone know of either

a) standalone sha256 and ripemd160 C or C++ code I can compile into a project, or

b) a small library I can static link into a project?

I'm not sure how to do that with OpenSSL; I'm on Windows 10 and it always seems to want a DLL it generates for shared libraries. Maybe I'm just not building correctly for static linking without DLLs.

Thank you for any pointers or tips.

I am trying to build small app to generate Bitcoin Address (for sake of understanding).
I use OpenSSL library.
I managed to convert private key to public key, hashed public key with sha256, and result was fine. But, then, problem appears when I try to run sha256 result trough ripemd160.
- I tested ripemd160 function with plain string and it works fine
- I did converted sha256 result to string
- Still I get wrong result

Here's my main:

int _tmain(int argc, _TCHAR* argv[]){    char sha256_buffer[65];    char ripemd160_buffer[41];    char *pvt_key = "18E14A7B6A307F426A94F8114701E7C8E774E7F9A47E2C2035DB29A206321725";    unsigned char *pub_hex = priv2pub((const unsigned char *)pvt_key, POINT_CONVERSION_UNCOMPRESSED );    //printf("%s\n", pub_hex);    std::string pub_key_string = hex_to_string(reinterpret_cast<char*>(pub_hex));    sha256(&pub_key_string[0], sha256_buffer);    printf("%s\n", sha256_buffer);    std::string hash256_string = hex_to_string(reinterpret_cast<char*>(sha256_buffer));    ripemd160(&hash256_string[0], ripemd160_buffer);    printf("%s\n", ripemd160_buffer);    return 0;}

Here's my ripemd160 function:

void ripemd160(char *string, char outputBuffer[41]){    unsigned char hash[RIPEMD160_DIGEST_LENGTH];    RIPEMD160_CTX ripemd160;    RIPEMD160_Init(&ripemd160);    RIPEMD160_Update(&ripemd160, string, strlen(string));    RIPEMD160_Final(hash, &ripemd160);    for (int i = 0; i < RIPEMD160_DIGEST_LENGTH; i++)    {        sprintf_s(outputBuffer + (i * 2), sizeof(outputBuffer + (i * 2)), "%02x", hash[i]);    }    outputBuffer[40] = 0;}

Here's my hex to string function:

string hex_to_string(const string& in) {    string output;    if ((in.length() % 2) != 0) {        throw runtime_error("String is not valid length ...");    }    size_t cnt = in.length() / 2;    for (size_t i = 0; cnt > i; ++i) {        uint32_t s = 0;        stringstream ss;        ss << hex << in.substr(i * 2, 2);        ss >> s;        output.push_back(static_cast<unsigned char>(s));    }    return output;}

I am using example from

This is the Ripemd-160 I suppose to get:
010966776006953D5567439E5E39F86A0D273BEE

This is the Ripemd-160 I am actually getting:
6c9814cf2a93131c8d3263158896e786de7a3f21

Hi I am making a simple program using python2.7 in which the first input is hex (32bytes) that will be hashed and increment by 1. The new value will be hashed again and increment again. The process will repeat until it satisfy the specified range.

However I'm getting an error with int()

TypeError: int() can't convert non-string with explicit base

Below is my program code

from coinkit.address import Addressimport hashlibh = hashlib.new('ripemd160') # <-- Create the hasha = Address.from_secret('0000000000000000000000000000000000000000000000000000000000000001') #where the input will be hashfor i in range (0, 10): # should have 10 outputs    intVal = int(a, 16) # convert to hex    intVal += 1 # increment by 1    h.update(hex(intVal)) # <-- Update the hash with the new incremented integer    a = Address.from_secret(h.hexdigest()) # <-- Get the digest and feed it back into from_secret    print a.pub, a.priv # <-- print new 'a' values

I did try to remove 16 it throws an error:

TypeError : int() argument must be a string or a number, not 'Address'

Please enlighten me. Thank you.

everything i have tried has given me wrong output values. i even copied C codes and changed them so that they would work in python and i still get wrong outputs. what is wrong?

I am looking for another approach to apply RIPEMD-160 to the second column of a csv file.

Here is my code

awk -F "," -v env_var="$key" '{    tmp="echo -n \047" $2 env_var "\047 | openssl ripemd160 | cut -f2 -d\047 \047"    if ( (tmp | getline cksum) > 0 ) {        $3 = toupper(cksum)    }    close(tmp)    print}' /test/source.csv > /ziel.csv

I run it in a big csv file (1Go), it takes 2 days and I get only 100Mo, that means i need to wait a month to get all my new CSV.

Can you help me with another idea and approach to get my data faster.

Thanks in advance
