Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Apply these universally across AWS services, such as using aws:MultiFactorAuthPresent to verify MFA status for resource access.”

A block of code is set as follows:

from aws_encryption_sdk import KMSMasterKeyProvider, encrypt
key_provider = KMSMasterKeyProvider(key_ids=[
  'arn:aws:kms:us-east-1:012345678912:key/abcd1234-a123-456a-a12b-a123b4cd56ef'
])
plaintext = 'This is a plaintext message.'
ciphertext, encryptor_header = encrypt(
    source=plaintext,
    key_provider=key_provider
)
print(f'Ciphertext: {ciphertext}')
