1# Python example: working with cleartext keysets 2 3This example shows how to generate or load a cleartext keyset, obtain a 4primitive, and use the primitive to do crypto. 5 6WARNING: this is not recommended, consider protecting your keysets with a key 7management system. 8 9## Build and run 10 11### Bazel 12 13```shell 14$ git clone https://github.com/google/tink 15$ cd tink/python/examples 16$ bazel build ... 17``` 18 19You can generate a cleartext keyset: 20 21```shell 22$ ./bazel-bin/cleartext_keyset/cleartext_keyset --mode generate \ 23 --keyset_path aes128_gcm_test_keyset.json 24``` 25 26You can then encrypt a file with the resulting keyset: 27 28```shell 29$ echo "some data" > testdata.txt 30$ ./bazel-bin/cleartext_keyset/cleartext_keyset --mode encrypt \ 31 --keyset_path aes128_gcm_test_keyset.json \ 32 --input_path testdata.txt --output_path testdata.txt.encrypted 33``` 34 35Or decrypt a file with: 36 37```shell 38$ ./bazel-bin/cleartext_keyset/cleartext_keyset --mode decrypt \ 39 --keyset_path aes128_gcm_test_keyset.json \ 40 --input_path testdata.txt.encrypted --output_path testdata.txt.decrypted 41 42$ diff testdata.txt testdata.txt.decrypted 43``` 44
