Unsupported hash type ripemd160 when checking if the provided posting key is allowed for the given Hive account #47

Closed agates closed 2 years ago

agates commented 2 years ago

Operating systems shipping with openssl 3.0 by default do not have the ripemd160 algorithm available.

This is causing podping-hivewriter to fail when using lighthive to convert the public key to a string to check its validity.

Removing string conversion works around the error, but then doesn't check if the public key belongs to the account.

See https://stackoverflow.com/a/72508879/4875332 for possible details on how to re-enable the ripemd160 algorithm in openssl.
