passphrase for private key

[daLocu]

Hi guys,

great work! Is it possible to set a passphrase for the private key?
(In the Putty KeyGen, for example, this is possible.)

kind regards

Thanks for raising this. I've had a quick look into it. It's quite trivial to do with .net 5 and .net 6 without adding any further dependencies, however it looks like it might be tricky to implement with backwards compatibility for NetFx 4.

What runtime are you targeting?

I'm wondering whether I should eventually drop support for older runtimes.

(for future me...) This issue covers how to implement it dotnet/runtime#51597

I use .net 6. thank you very much

Hi, please do you plan to add this feature in the near future?

I'd also like to see this feature. (.NET 7.0/8.0)

Just started implementing key generation into an application. Would also love to see passphrase support (.NET 8)

I am trying to use this library and able to generate Private and Public Keys. However, need functionality to add Passphrase to private key.

is this already added?

I've started looking into this once again, what format would you need the private keys to be encrypted in? OpenSSH or RSA/PEM (legacy)?

[Banda943224]

@ShawInnes Can you help me with RSA/PEM one plz.

@ShawInnes did you get a chance to look into the request?

[maranashokan]

@ShawInnes Thank you for checking. We also looking to add passphrase to private key, appreciate if any update.

[Banda943224]

@ShawInnes any update on the request? can you please look into ASAP?

@ShawInnes This would be a great addition to what I am also trying to do. Were you able to get the passphrase to work? How?

Just a quick update - I've spent considerable time on this and haven't managed to get it to work yet. I have tried a few approaches but I can't work out how to get the encrypted file to decrypt using 3rd party tools. I'm happy to review and merge any pull requests from others on this one.
