Sectigo SSL Certificate Reviews

I purchased a Comodo PositiveSSL cert through a reseller who offered it for considerably less money than buying direct from Comodo. The process was straightforward: submit a CSR, answer a confirmation email sent to a domain contact address, and the cert was issued. The whole process took around 15 minutes. Added perk: Comodo will sign your cert using SHA2 (with all SHA2-signed intermediate certs chaining back to the root) if one adds the appropriate flag ("-sha256") to OpenSSL when generating a private key/CSR. For example, this command will generate a 2048-bit RSA key and request a SHA256 signature: "openssl req -new -newkey rsa:2048 -nodes -sha256 -out www.mydomain.com.sha256.csr -keyout www.mydomain.key"
