I got the private and public key
Now I want to get a signature but when i pass the private key to get the signature i get an error
{
"status": "error",
"message": "unacceptable key",
"error": "unacceptable key"
}
I send it in this format
-----BEGIN RSA PRIVATE KEY-----\nkey\n-----END RSA PRIVATE KEY-----\n
I use module криптография version 1
