Java AEAD example

This example shows how to encrypt data with Tink using Authenticated Encryption with Associated Data (AEAD).

It demonstrates the basic steps of using Tink, namely loading key material, obtaining a primitive, and using the primitive to do crypto.

The key material was generated with Tinkey:

shell

tinkey create-keyset --key-template AES128_GCM --out-format JSON \
    --out aead_test_keyset.json

Build and run

Bazel

shell

git clone https://github.com/google/tink
cd tink/examples/java_src
bazel build ...

Encrypt a file:

shell

echo "some data" > testdata.txt

./bazel-bin/aead/aead_example encrypt \
    ./aead/aead_test_keyset.json \
    testdata.txt testdata.txt.encrypted

Decrypt a file:

shell

./bazel-bin/aead/aead_example decrypt \
    ./aead/aead_test_keyset.json \
    testdata.txt.encrypted testdata.txt.decrypted

diff testdata.txt testdata.txt.decrypted
