I thought this patch could give an ability to handle OAEP label with
openssl(1) pkeyutl command, and encryption works fine, but decryption fails.
--
openssl genrsa -out rsakey.pem
echo "abcd" | openssl pkeyutl -encrypt -inkey rsak
Provide methods: EVP_PKEY_CTX_{g,s}et_rsa_oaep_md,
EVP_PKEY_CTX_{g,s}et0_rsa_oaep_label.
