Encrypt to multiple public keys

[get-fooby]

Hello, while I haven't extensively tested this, I don't think it can allow encrypting to multiple public keys. I understand it's totally do-able in PGP world - but is the script able to do this as is? Regards

Don't see it as an option in https://github.com/mattosaurus/PgpCore

Probably requires opening an issue on it, and if they implement it - we'll just add it.

Per this post (https://githubhelp.com/mattosaurus/PgpCore/issues/18) encrypting to multiple keys should be possible with pgpcore >1.4

You're correct - it seems to be as simple as changing FilePathPublic to [string[]] instead of [string] and modifying logic to just convert FilePathPublic to PublicKey (FileInfo).

It looks like this was pushed to master. I am attempting to encrypt a string using your examples but receiving an error

PS C:\keys> $String = Protect-PGP -FilePathPublic @("$PSScriptRoot\Keys\PublicPGP1.asc", "$PSScriptRoot\Keys\PublicPGP2.asc") -String "This is string to encrypt"

Protect-PGP : Cannot process argument transformation on parameter 'FilePathPublic'. Cannot convert value to type

Are you using github version or PSGallery one? I have not published anything yet.

From the error message it would seem you're using "old version"

function Test {
    [CmdletBinding()]
    param(
        [string] $Test
    )
}

Test -Test @("$PSScriptRoot\Keys\PublicPGP.asc", "$PSScriptRoot\Keys\PublicPGP2.asc")

You're applying array to a string, and new version takes array instead of string.
