How to use on-demand rotation for AWS KMS imported keys

Today, we’re announcing support for on-demand rotation of symmetric encryption AWS Key Management Service (AWS KMS) keys with imported key material (EXTERNAL origin). This new capability enables you to rotate the cryptographic key material of these keys without changing the key identifier (key ID or Amazon Resource Name (ARN)). Rotating keys helps you meet compliance […]

The curious case of faster AWS KMS symmetric key rotation

Today, AWS Key Management Service (AWS KMS) is introducing faster options for automatic symmetric key rotation. We’re also introducing rotate on-demand, rotation visibility improvements, and a new limit on the price of all symmetric keys that have had two or more rotations (including existing keys). In this post, I discuss all those capabilities and changes. […]

How to protect HMACs inside AWS KMS

April 20, 2022: In the section “Use the HMAC key to encode a signed JWT,” we fixed an error in the code sample. Today AWS Key Management Service (AWS KMS) is introducing new APIs to generate and verify hash-based message authentication codes (HMACs) using the Federal Information Processing Standard (FIPS) 140-2 validated hardware security modules […]

Encrypt global data client-side with AWS KMS multi-Region keys

Today, AWS Key Management Service (AWS KMS) is introducing multi-Region keys, a new capability that lets you replicate keys from one Amazon Web Services (AWS) Region into another. Multi-Region keys are designed to simplify management of client-side encryption when your encrypted data has to be copied into other Regions for disaster recovery or is replicated […]
