Depending on how the ec key gets created or imported
key2hash()
returns thecurve_name
property either in lower- or uppercase.The value is lowercase if the curve parameters are imported or set by the user and uppercase if the name is directly returned from libtomcrypt.
Since
generate_key()
expects the name in lowercase, we convert the value to lowercase as well.As a sideeffect this also avoids unneccessary curve parameter lookups in
Crypt::PK::ECC::_curve_name_lookup()
.
