1# Java AEAD example 2 3This example shows how to encrypt data with Tink using Authenticated Encryption 4with Associated Data (AEAD). 5 6It demonstrates the basic steps of using Tink, namely loading key material, 7obtaining a primitive, and using the primitive to do crypto. 8 9The key material was generated with Tinkey: 10 11```shell 12tinkey create-keyset --key-template AES128_GCM --out-format JSON \ 13 --out aead_test_keyset.json 14``` 15 16## Build and run 17 18### Bazel 19 20```shell 21git clone https://github.com/google/tink 22cd tink/examples/java_src 23bazel build ... 24``` 25 26Encrypt a file: 27 28```shell 29echo "some data" > testdata.txt 30 31./bazel-bin/aead/aead_example encrypt \ 32 ./aead/aead_test_keyset.json \ 33 testdata.txt testdata.txt.encrypted 34``` 35 36Decrypt a file: 37 38```shell 39./bazel-bin/aead/aead_example decrypt \ 40 ./aead/aead_test_keyset.json \ 41 testdata.txt.encrypted testdata.txt.decrypted 42 43diff testdata.txt testdata.txt.decrypted 44``` 45
