Follow the instructions to contribute documents and information. You will be given a codename consisting of several random words. You can return to the SecureDrop site at a later date and enter this codename to see if we have responded to your submission. You can also respond to our questions or comments and provide more information if necessary. For your own security, please consider the ramifications of discussing your contribution with anyone else. For added security and privacy, consider using the Tails operating system to contribute. If you are knowledgeable about security software, consider encrypting your submission with our public PGP key prior to submission. For more information on how SecureDrop works and how to use it as a source, see the official documentation maintained by the Freedom of the Press Foundation.
