Licensing
DigiCert® Software Trust Manager is based on a subscription licensing model. For updates to your license agreement, contact DigiCert Sales.
Signature units
Signature units are relative to the number of hashes that are signed with a production keypair. Every hash that you sign will consume one signature unit.
Nota
Signature units have a soft limit. This means that you are not restricted to the unit amount in your account and can exceed it however you will incur overages.
Test signature units
Test signature units are relative to the number of hashes that are signed with a test keypair. Every hash that you sign will consume one signature unit.
Nota
Test signature units have a soft limit. This means that you are not restricted by the unit amount in your account and you can exceed it, however you will incur overages.
Cryptographic units
Cryptographic units is a count of all operations performed by an account which are related to cryptographic assets excluding signatures.
Cryptographic events include:
Create a keypair
Update a keypair
Export a keypair
Import keypair
Create a certificate
Update a certificate
Import a certificate
Revoke a certificate
Generate a CSR
Nota
Cryptographic units have a soft limit. This means that you are not restricted to the unit amount in your account and you can exceed it, however you will incur overages.
HSM keypair units
HSM keypair units refer to how many keypairs you create on our HSMs. We provide sufficient space for the number of public trust certificates you are licensed to create as part of your DigiCert® Software Trust Manager license. The more signature units you buy, the more public certificates and HSM keypair space you will be allocated.
Nota
HSM keypair units have a hard limit. This means that you will be restricted to the amount of units in your account and you cannot exceed it unless your license is amended by contacting Sales.
