Signing Platform

A signing platform is a predefined set of instructions that specifies the signature format and signing algorithms that AWS Signer should use to sign a zip file. For more information go to Signing Platforms in AWS Signer.

AWS Signer provides a pre-defined set of signing platforms. They are available in the CDK as -

Platform.AWS_IOT_DEVICE_MANAGEMENT_SHA256_ECDSA
Platform.AWS_LAMBDA_SHA384_ECDSA
Platform.AMAZON_FREE_RTOS_TI_CC3220SF
Platform.AMAZON_FREE_RTOS_DEFAULT

Signing Profile

A signing profile is a code-signing template that can be used to pre-define the signature specifications for a signing job. A signing profile includes a signing platform to designate the file type to be signed, the signature format, and the signature algorithms. For more information, visit Signing Profiles in AWS Signer.

The following code sets up a signing profile for signing lambda code bundles -

signing_profile = signer.SigningProfile(self, "SigningProfile",
    platform=signer.Platform.AWS_LAMBDA_SHA384_ECDSA
)

A signing profile is valid by default for 135 months. This can be modified by specifying the signatureValidityPeriod property.
