A Symmetric Encryption Tool.

Note: When Darlene encrypts data, be it a text/binary file, array, string/JSON or Buffer, she outputs a darlene (drln) file, which allows Darlene preserve the necessary metadata for decrypting the data later on.

Tip: After decrypting, remember to convert back to Buffer; hex/base64 string is returned.

Check the sample code for more info.

• Darlene can encrypt just about anything:

  • JSON
  • String/Plain text
  • Buffer
  • Arrays (using JSON)
  • Plain Text, JSON, & Binary files

• and only decrypt Darlene (drln) files.

Ensure to include the binary flag (-B) when encrypting binary files. Usually these are files that display garbage data when opened in a text editor, e.g. '.png', '.pdf', '.docx', '.exe', '.AppImage', etc. As for JSON content, use the json flag (-J or --json) when encryptin JSON files.

Without the above flags, both encrypted JSON and Binary files would not be properly decrypted back to their original formats.

Caution: If you are decrypting binary content that requires exec (+x) permissions, include the -X or --exec flag. You could also use the flag if you aren't sure whether the binary content being decrypted would require exec permissions.

After the v0.6.0 release, the drln file structure was changed to make reading the drln file data easier, and to also make discovery of drln files easier as they now begin with the 4 Byte magic number '44 4E 17 29' (or 'DN\u0017)' when decoded using 'utf-8').

If you are trying to decrypt an older drln file created by darlene v0.5.x or older, include the -legacy or -L flag.

Note: If you are not sure whether a drln file is a legacy drln file, try decrypting normally (i.e. $ darlene -f [drln file] -o [output file] -D ...), if you get the following error: "darlene: Darlene file contains an invalid magic number.", then it is likely that the drln file is a legacy file, as legacy files had no magic number, which means you should include the legacy flag (-L or --legacy). Additionally, if after adding the legacy flag you get the following error: "darlene: Darlene file does not have a valid version number.", then it is likely that the file is not a drln file.
