I would like to sign and verify a pdf with elliptic curve. I got some code but it dosen't work.
Create private key:
openssl ecparam -genkey -name secp384r1 -noout -out private.pem
Create public key:
openssl ec -in private.pem -pubout -out public.pem
openssl dgst -ecdsa-with-SHA1 test.pdf > hash openssl dgst
openssl dgst -ecdsa-with-SHA1 -inkey private.pem -keyform PEM -in hash > signature
openssl dgst -ecdsa-with-SHA1 -verify public.pem -signature signature.bin data
The part to sign and verify dosen't work.
