-=item "type" (B<OSSL_PKEY_PARAM_FFC_TYPE>) <utf8_string>
+=item "type" (B<OSSL_PKEY_PARAM_FFC_TYPE>) <UTF8 string>
Sets the type of parameter generation. The shared valid values are:
For "fips186_4" this can be either 224 or 256.
For "fips186_2" this has a size of 160.
-=item "digest" (B<OSSL_PKEY_PARAM_FFC_DIGEST>) <utf8_string>
+=item "digest" (B<OSSL_PKEY_PARAM_FFC_DIGEST>) <UTF8 string>
Sets the Digest algorithm to be used as part of the Key Generation Function
associated with the given Key Generation I<ctx>.
This must also be set for key validation.
-=item "properties" (B<OSSL_PKEY_PARAM_FFC_DIGEST_PROPS>) <utf8_string>
+=item "properties" (B<OSSL_PKEY_PARAM_FFC_DIGEST_PROPS>) <UTF8 string>
Sets properties to be used upon look up of the implementation for the selected
Digest algorithm for the Key Generation Function associated with the given key
