     1  # Unencrypted Keys Generator
     2  
     3  This tool is used to generate JSON file of unencrypted, base64 encoded, validator
     4  signing and withdrawal keys. These keys can be fed into the Prysm validator
     5  client for fast development startup times instead of using the Prysm keystore.
     6  
     7  Usage:
     8  
     9  ```
    10  bazel run //tools/unencrypted-keys-gen -- --num-keys 64 --output-json /path/to/output.json
    11  ```
    12  
    13  Which will create 64 BLS private keys each for validator signing and withdrawals. 
    14  These will then be output to an `output.json` file. Both arguments are required. 
    15  The file can then be used to start the Prysm validator with the command:
    16  
    17  ```
    18  bazel run //validator -- --unencrypted-keys /path/to/output.json
    19  ```
