my erlang version is 24 and it does not support ripemd160 hash algorithm and i don’t know why. the erlang crytpo document says it is a supported algorithm.
crypto:start(),
B = crypto:hash(ripemd160, H).
it gives me this error:
** exception error: notsup
in function crypto:notsup_to_error/1 (crypto.erl, line 2147)
i searched online for this and could not found the solution and tried couple of method but could not solve it.
thanks in advance.
>Solution :
Your Erlang installation seems to match release 24.2.1, and thus is affected by this part of the crypto release notes:
The hash algorithms
md4andripemd160are disabled temporarily when compiled with OpenSSL 3.0.
Support for these algorithms was reinstated in release 24.3.
Note that support for OpenSSL 3 (as opposed to 1.1.1 and earlier versions) was considered experimental for all Erlang 24 releases. Release 25.1 was the first one that said:
Crypto is now considered to be usable with the OpenSSL 3.0 cryptolib for production code.
ENGINE and FIPS are not yet fully functional.
