SSL.com currently supports AWS CloudHSM, Azure Dedicated HSM, and Google Cloud HSM for issuance of Adobe-trusted document signing certificates and EV code signing certificates. All of these cloud HSM services provide FIPS 140-2 Level 3 validated HSM hardware for generating and storing encryption keys. This guide provides an overview of key generation, attestation, and certificate ordering for these cloud HSM platforms, and includes pricing information for certificates installed on cloud HSMs.
Amazon Web Services (AWS) CloudHSM service does not currently provide any means by which SSL.com can automate attestation of keys generated on the HSM. For this reason, we require a remotely-witnessed key pair generation ceremony before we can issue document signing and EV code signing certificates for installation on AWS CloudHSM. This remote-witnessing procedure will incur an extra charge for time spent by SSL.com staff on the ceremony.
During the ceremony, SSL.com staff will observe the generation of one or more cryptographic key pairs with non-exportable private keys on a CloudHSM instance via videoconferencing software. Following the ceremony, the customer may submit a certificate signing request (CSR) for signing and issuance by SSL.com. Please refer to Amazon’s AWS CloudHSM Documentation for CSR generation instructions.
SSL.com’s fee for key generation ceremonies on AWS CloudHSM is $1200.00 USD.
Microsoft’s Azure Dedicated HSM service uses the SafeNet Luna Network HSM 7 Model A790 HSM. The Luna
cmu command-line tool can be used to generate a cryptographic key pair and certificate signing request (CSR) for document signing or EV code signing, along with information required by SSL.com for attestation. Please refer to Thales’ Certificate Management Utility (CMU) documentation for full instructions on working with the
When generating your key pair with the cmu generatekeypair utility, be certain to make sure that the private key is not extractable (the default setting is non-extractable). You should generate your CSR with the cmu requestcertificate command.
After generating your key pair and CSR, request a public key confirmation (PKC) file for the new keys with the cmu getpkc command. This file can be used by SSL.com to confirm that the key pair was generated on compliant hardware and the private key is not exportable.
After generating your key pair, CSR, and PKC file, you can submit the CSR and PKC to SSL.com for validation and signing.
SSL.com’s fee for Azure Dedicated HSM PKC confirmation is $500.00 USD.
Google’s Cloud HSM service uses devices manufactured by Marvell (formerly Cavium), which can produce signed attestation statements for cryptographic keys that SSL.com can verify before issuing document signing or EV code signing certificates. Please refer to Google’s Cloud Key Management documentation when generating your key pair and attestation statement:
After generating your key pair, CSR, and attestation statement, you can submit them to SSL.com for validation and signing. GitHub user mattes has provided an open-source utility for creating a CSR and signing it with a private key from Google Cloud HSM.
SSL.com’s fee for Google Cloud HSM attestation is $500.00 USD.
Bring Your Own Auditor (BYOA)
BYOA is a valid alternative for clients, but it requires thorough preparation, otherwise, there is a significant risk of rejection for the generated key. This could happen if the device used is not compliant, or the auditor is not qualified, or the auditor’s report does not cover the requirements of the process. In such a case, the ceremony and its witnessing have to be repeated, resulting in added costs and delays for the client.
To avoid such scenarios, SSL.com’s customer support and/or validation specialists communicate with the customer before the KGC to provide guidance and ensure the following:
- The auditor is approved according to the criteria described below
- The ceremony preparations requirements as wells as the ceremony script are clear and followed thoroughly, so as the KGC environment is well prepared
- Any restrictions and/or BYOA-specific terms and conditions are clear and accepted by the customer
