Decrypting a Data Blob in Amazon KMS

The following example uses the Amazon SDK for Ruby decrypt method, which implements the Decrypt operation, to decrypt the provided string and emit the result.

require "aws-sdk-kms" # v2: require 'aws-sdk'

# Decrypted blob

blob = "01020200785d68faeec386af1057904926253051eb2919d3c16078badf65b808b26dd057c101747cadf3593596e093d4ffbf22434a6d00000068306606092a864886f70d010706a0593057020100305206092a864886f70d010701301e060960864801650304012e3011040c9d629e573683972cdb7d94b30201108025b20b060591b02ca0deb0fbdfc2f86c8bfcb265947739851ad56f3adce91eba87c59691a9a1"
blob_packed = [blob].pack("H*")

client = Aws::KMS::Client.new(region: "us-west-2")

resp = client.decrypt({
                        ciphertext_blob: blob_packed
                      })

puts "Raw text: "
puts resp.plaintext
