AWS Signer vs SSL.com eSigner for Code

AWS Signer is a managed code-signing service for verifying code integrity and publisher trust. It supports signing AWS Lambda deployment packages, code for supported IoT devices, and OCI container images using Notation. Lambda verifies signatures and package integrity when signed code is deployed. For containers, Signer works with Notation in registries such as Amazon ECR, with signatures stored alongside images for verification.

Administrators control access to Signer resources and actions through AWS Identity and Access Management policies. Signing profiles can be managed in the Signer console, AWS CLI, or API. Signer manages certificates and keys for Lambda and container workflows; IoT workflows can use a code-signing certificate imported into AWS Certificate Manager. Documentation also lists integrations with AWS Certificate Manager and CloudTrail, plus Amazon EKS image verification. Notation CLI and Signer plugin installers are listed for Linux, macOS, and Windows. API actions have per-second quotas by account and Region, with no minimum request rate. Use with specified AWS services has no additional charge, though related charges may apply.
