Hi,

To use the certificate with the IIS6 Smtp server, one has to install the certificate in the local machine, personal store.
Is this something that one can easily add to the application, or would it require significant changes?

Command

Output Log:

using server https://acme-v01.api.letsencrypt.org/
trying to create new registration
error:
**urn:acme:error:malformed**
Provided agreement URL [https://letsencrypt.org/documents/LE-SA-v1.0.1-July-27-2015.pdf] does not match current agreement URL [https://letsencrypt.org/documents/LE-SA-v1.1.1-August-1-2016.pdf]

I'm looking for a simple way to create let's encrypt certificates on Windows. Where can I find acme.exe which is mentioned in the documentation?

Isn't it nice to get security software with malware combined?

In file class CsrTests

line 62 is:
sut.Save(key.ExportParameters(true), "test.startliste.info", KeyExport.Format.PEM);

but should be:
sut.Save(key.ExportParameters(true), "test.startliste.info", KeyFormat.PEM);

The parameter IEnumerable Domains could not be parsed.

Type conversion error :-(

Are there plans to update the library to target the new csproj format / NETSTANDARD 2.0?

Am up for doing the port if this is a contribution that the project will accept.

Trying to run the cleint and I get:

From a quick search it's a .NET 4.6/4.5 issue

I am try install in IIS8.5. why show wrong ? How I do it?

Thoughts on merging Oocx.Asn1PKCS & Oocx.Common into Oocx.Acme?

This would let us internalize the internalize the key & certificate encoding/decoding API surface and give us a clean path to replace with corefx implementations when they land.

Security crypto - Roadmap: https://github.com/dotnet/designs/issues/11

Is it somehow possible to encode alternative domain names, like to have identical certificate for:
www.example.com and example.com?

Hello
Was working for us for a long while
After the last windows update we get this:

could not create pfx file: System.Security.Cryptography.CryptographicException: Key not valid for use in specified state.

Ideas?

This worked great for me, too easy. I did have to do an optional update to install .net 4.6.

Is this going to auto renew on its own?

Notes:
I did this on an AWS EC2 T2 micro running windows 2012 R2.

I copied the acme.exe from the Releases link into a folder called LetsEncrypt on my C drive, then opened a command prompt there (Shift + Right Click - Open Command Window here) and then did as instructed: acme.exe -a mywebsite.com -m mailto:[email protected]

During the process, it asks for a password, it was not clear what this was to me - I was thinking it was being mailed to me so I checked my email. Eventually I figured maybe it was asking me to enter a password, so I made one up and it accepted it.

I'm still unclear what the purpose of the email is, I still have not received one, but the site is available over ssl with no errors that I can see.

Very nice project. I will be looking at using it in a small server project, and it looks like I could just provide my own IChallengeProvider to make it work.

If anyone has hints or has done this, let me know (via here presumably). If I proceed and succeed, I will post any suitable additions.

Don't know why but it hangs on first Directory response and this fix makes it work:

Hi can someone rebuild the project with the new terms and conditions and submit it as a release.

Thank you
