Using iText 7 and AWS KMS to digitally sign a PDF document: Part 4

This example was written for the article "Using iText 7 and AWS KMS to digitally sign a PDF document" and demonstrates signing a PDF with iText using an AWS KMS Key Pair.

Assuming your AWS KMS signing key pair has the alias SigningExamples-ECC_NIST_P256 and is indeed an ECC_NIST_P256 key pair you can use the AwsKmsSignature code from Part 3 to sign a PDF like this:

Note: The article assumes that you have stored your credentials in the default section of your ~/.aws/credentials file and your region in the default section of your ~/.aws/config file. Otherwise, you'll have to adapt the KmsClient instantiation or initialization in the code examples written for this article.
