RIPE online MD160 Hash Generator

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

I am trying to understand how the crypto algorithms RIPEMD and SHA256 work. The bitcoin method for computing PKHash is RIPEMD160(SHA256(PublicKey)).

I am trying to first implement the RIPEMD of SHA256(PublicKey).

pkHashStep1=hashlib.sha256(public_key.decode('hex')).digest()print 'MyTransaction pkHashStep1 {}'.format(pkHashStep1)MyTransaction pkHashStep1 ▒▒▒so▒/▒▒e▒▒▒¡▒7▒?9▒▒.▒ӟ!n▒h

This outputs a string that I cannot use directly, but the hashlib library can use this. Trying pkHashStep1.decode('hex') and bin(pkHashStep1) throws an error. How does it convert the hash to a usable hexstring/bin??

Currently, I have publicKey as input to my RipeMD method, instead of the pkHashStep1, and have to separately do

input=hashlib.sha256(publicKey.decode('hex')).hexdigest()

FYI: I know there is a ripemd method in hashlib. Suggesting I use it is not an answerhttps://stackoverflow.com/a/2124289/4219479

According to the Python documentation, only a few hash algorithms are guaranteed to be supported by the hashlib module (MD5 and SHA***). How would I go about detecting if other algorithms are available? (like RIPEMD-160) Of course, I could try to use it using the RIPEMD-160 example from the documentation, but I'm not sure how it would complain. Would it throw an exception, if yes, which exception?

Here's the code I tried in Python but I get AttributeError:

>>> import hmac>>> import hashlib>>> h=hashlib.new('ripemd160')>>> hmac.new("bedford","Hello",hashlib.ripemd160)    Traceback (most recent call last):    File "<stdin>", line 1, in <module>    AttributeError: module 'hashlib' has no attribute 'ripemd160'

I have searched the Python documentation and lots of forums but do not find much on ripemd160 and Python.
