We have also seen encrypted text editor for Linux. We have seen how to password protect folders in Ubuntu earlier. because we're almost never willing to change defaults for choices that apply to persisted files.Brief: This simple tutorial shows you how to create a password protected zip file in Linux both in command line and graphical way.

Prefer a parameter input (explicitly specified) over a property (with a default value). The encryption mode must be an input for new content.If you feel you need it for high-level usability, well, I guess.Prefer a mode where you don't persist the password to a field.Being able to take it as a ReadOnlySpan would be nicer, but requires moving the encrypt/decrypt to verbs on ZipFileEntry (which may be useful anyways, for degenerate files that use multiple different passwords). This is all unfortunate that you're holding the password string in memory. Public enum ZipEncryptionMode // Update/Create modes will throw if newFileEncryptionMode is default public static ZipArchive Open ( string archiveFileName, Encoding entryNameEncoding, string password, ZipEncryptionMode newFileEncryptionMode = default ) The preference in cryptography API is to never have a default algorithm choice, so creating new encrypted ZIP files would require using a method that took that as an input. This allows for callers to change from Aes256 to whatever algorithm replaces Aes256 in the future without creating compatibility/tool-interop concerns.

For creating new encrypted ZIP files you probably want to accept an encryption algorithm/mode value.

so we might just add it this release with some of the new API. We currently don't expose AES-CTR as public API.

Key generation uses PBKDF2, which is the algorithm used by 2898DeriveBytes.

In practice, it seems unlikely so asking for a single decryption password seems reasonable.

Technically speaking, I think each entry could be encrypted with a different password.

The PKZIP encryption seems to require a license to implement.Īll further comments relate to the WinZIp version:.

I'm not quite sure what's being asked of me here.
