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.
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.
