Is there a way to encrypt a file using the openssl command with an
elliptic curve public key? Here's what I get when I try using OpenSSL
1.1.0c :
normg>./openssl pkeyutl -encrypt -pubin -inkey secp256k1-public-key.pem
-in a.txt -out a.txt.enc
pkeyutl: Error initializing context
140339244734272:error:0608B096:digital envelope
routines:EVP_PKEY_encrypt_init:operation not supported for this
keytype:crypto/evp/pmeth_fn.c:139:
normg>cat secp256k1-public-key.pem
-----BEGIN PUBLIC KEY-----
