Integrate CloudHSM PKCS #11 Library 5.0 with serverless workloads

Amazon Web Services (AWS) recently released PCKS #11 Library version 5.0 for AWS CloudHSM. This blog post describes the changes implemented in the new library. We also cover a simple encryption example with the Advanced Encryption Standard (AES) algorithm in Galois/Counter Mode (GCM), dockerized, running on AWS Fargate. The primary change from the previous SDK […]

Signing executables with HSM-backed certificates using multiple Windows instances

Customers use code signing certificates to digitally sign software, documents, and other certificates. Signing is a cryptographic tool that lets users verify that the code hasn’t been altered and that the software, documents or other certificates can be trusted. This blog post shows you how to configure your applications so you can use a key […]

How to migrate symmetric exportable keys from AWS CloudHSM Classic to AWS CloudHSM

In August 2017, we announced the “new” AWS CloudHSM service, which had a lot of improvements over AWS CloudHSM Classic (for clarity in this post I will refer to the services as New CloudHSM and CloudHSM Classic). These advantages in security, scalability, usability, and economy, included FIPS 140-2 Level 3 certification, fully managed high availability […]

Signing executables with Microsoft SignTool.exe using AWS CloudHSM-backed certificates

Code signing is the process of digitally signing executables and scripts to confirm the software author and to demonstrate that the code has not been altered or corrupted since it was signed. Packaged software uses branding and trusted sales outlets to assure users of its integrity, but these guarantees are not available when code is […]

How to clone an AWS CloudHSM cluster across regions

You can use AWS CloudHSM to generate, store, import, export, and manage your cryptographic keys. It also permits hash functions to compute message digests and hash-based message authentication codes (HMACs), as well as cryptographically sign data and verify signatures. To help ensure redundancy of data and simplification of the disaster recovery process, you’ll typically clone […]

Understanding AWS CloudHSM Cluster Synchronization

AWS CloudHSM provides fully managed, single-tenant hardware security modules (HSMs) in the AWS cloud. A CloudHSM cluster contains either one or multiple HSMs. Multiple HSMs support higher throughput levels for cryptographic operations and provide redundancy. For clusters with multiple HSMs, the CloudHSM service supports server-side automated synchronization of keys and policies. Users, however, are synchronized […]

Benefits of a Key Hierarchy with a Master Key (Part Two of the AWS CloudHSM Series)

Previously, Todd Cignetti, AWS Security Product Manager, wrote a post that covered some typical use cases for AWS CloudHSM, a service that helps you securely generate, store, and manage the cryptographic keys used for data encryption such that they are accessible only by you. In this post, Todd continues the series on AWS CloudHSM with […]
