Starting in SGOS 220.127.116.11, you can specify the signing hash when you create the individual Certificate Signing Request (CSR). The following information is for SGOS versions 18.104.22.168 through 22.214.171.124.
CSRs on the ProxySG appliance are by default generated for use with an SHA-1 cryptographic hash function. Using the SHA-1 hash function is not an issue if you are requesting a certificate from the Certificate Authority (CA) because the CA applies the required hash function (SHA256) to the certificate when signing the CSR.
A hidden command exists that allows you to configure the appliance to use the SHA-2 hash function when creating a CSR. To change the default SHA-1 hash function to SHA-2, log in to the CLI and type the following commands:
