AWS::IoT::OTAUpdate CustomCodeSigning

Describes a custom method used to code sign a file.

Syntax

To declare this entity in your CloudFormation template, use the following syntax:

JSON

{
  "CertificateChain" : CodeSigningCertificateChain,
  "HashAlgorithm" : String,
  "Signature" : CodeSigningSignature,
  "SignatureAlgorithm" : String
}

YAML

  CertificateChain: 
    CodeSigningCertificateChain
  HashAlgorithm: String
  Signature: 
    CodeSigningSignature
  SignatureAlgorithm: String

Properties

CertificateChain

The certificate chain.

Required: No

Type: CodeSigningCertificateChain

Update requires: Replacement

HashAlgorithm

The hash algorithm used to code sign the file. You can use a string as the algorithm name if the target over-the-air (OTA) update devices are able to verify the signature that was generated using the same signature algorithm. For example, FreeRTOS uses SHA256 or SHA1, so you can pass either of them based on which was used for generating the signature.

Required: No

Type: String

Update requires: Replacement

Signature

The signature for the file.

Required: No

Type: CodeSigningSignature

Update requires: Replacement

SignatureAlgorithm

The signature algorithm used to code sign the file. You can use a string as the algorithm name if the target over-the-air (OTA) update devices are able to verify the signature that was generated using the same signature algorithm. For example, FreeRTOS uses ECDSA or RSA, so you can pass either of them based on which was used for generating the signature.

Required: No

Type: String
