Not a Private Key

When jarsigner says "Key Associated with [alias] not a private key" it almost certainly meant to say that you got your password wrong.

Sending email via GMail in C#/.NET using SmtpClient

Updated on Friday, September 13, 2019

Gmail Logo

Here’s a quick code snippet that configures SmtpClient to send email using Gmail’s SMTP server:

This can be frustratingly difficult to get right so I’ll run through each setting quickly.

DeliveryMethod: Set to SmtpDeliveryMethod.Network, the alternatives are copying the email to a directory for pickup by a different application. We want to connect directly to Gmail.

UseDefaultCredentials: False, as we’ll be providing our own credentials later. Setting properties in the right order is apparently important for SmtpClient, although the Microsoft documentation doesn’t mention this. Make sure you set UseDefaultCredentials to false before setting the Credentials property.

EnableSsl: True. SSL or TLS is required.

Host: smtp.gmail.com for this example. Note that this server restricts you to sending 2,000 emails per day. There is a less restrictive option for G Suite customers (smtp-relay.gmail.com) and a more restrictive server that can only send messages to Gmail or G Suite addresses (aspmx.l.google.com).

Port: Google says to use 465 for SSL and 587 for TLS. I’ve found that 587 with EnableSSL set to true works fine.

Credentials: Your Gmail address and password in a NetworkCredential. If your account has 2 step (multi factor) authentication then this won’t work. You can generate an app password easily and use this instead of your regular password. It’s also possible to use OAuth.

In the comments below Shika Helmy suggests also setting the Timeout property to 20000.

You can now use smtp.Send() to send the email.

Because it’s likely to be your personal account and there is a 2,000 message cap on sending I’d only recommend using this for small scale projects. You don’t want to get your Gmail account blocked. For higher volume I’d look at using SendGrid or similar.

One last note - while I’ve used SmtpClient for all sorts of trivial email needs over the years the latest Microsoft documentation marks it obsolete and warns:

SmtpClient and its network of types are poorly designed, we strongly recommend you use https://github.com/jstedfast/MailKit and https://github.com/jstedfast/MimeKit instead

Hope this expanded article helps. I still come back here periodically to cut and paste rather than mess up the property order again...

Support SHIELD–a small measure of patent sanity

Updated on Thursday, November 12, 2015

A friend pointed me at the SHIELD (PDF) act today. This bill would make unsuccessful patent trolls pay defendants’ legal bills. It’s not as good as my radical plan to fix patents, but it’s a step in the right direction. If you care, let your congressperson know. Here’s the note I just sent to mine:

Dear Rep. Pelosi,

I'm writing to let you know that I support the SHIELD act Introduced by Rep. Peter DeFazio (D-OR) and co-sponsored by Rep. Jason Chaffetz (R-UT). As an entrepreneur and professional software developer I have personally experienced the job destroying effects of ill founded patent litigation. Any step to reduce this drag on our industry is a welcome step.

Twitter's API has got too painful for me

Updated on Thursday, November 12, 2015

Twitter's API has got too painful for me

I've developed a bunch of stupid, niche and vaguely promising apps on top of the Twitter API. During that time I've slogged through various painful and rapid shifts like changing IDs, authentication schemes and diktats handed down on which parts of the ecosystem Twitter would like to control. I've had to roll my own OAuth and even re-word a blog post to Twitter Support's satisfaction to get a blocked application unblocked again. It's been a pretty frustrating experience but worth rolling with the punches until the past week.

Twitter suspended Cleat, a tool for posting from the command line. So I emailed to ask why, too much effort for them to explain the rationale at the time they're putting the suspension in place I guess. I got an auto-response asking for information they must have already had and I replied to this. A few days later I still hadn't heard back so I emailed again and the ticket had been automatically closed. 

So far just the standard fuck-off-and-die support that you'd expect from a growing company that no longer wants to talk to it's users. But the auto-reply directed me to https://support.twitter.com/forms/ to file a new ticket. None of the options there relate to developers or a suspended application. I tried filing a ticket under 'deactivated account' which seemed the closest.

That form has a hard-coded 'With love,' valediction. Whoever thought that was cute should go through the process of trying to get help a few times. 

This attempt auto-responded to say that my account was not suspended, and would I like to fuck-off-and-die or got back to the forms center?

So I tried another form that actually seemed to submit but haven't heard anything back.

I'd be happy to update my software if I know which vague shifting facet of the Twitter terms of use I'd fallen foul of. Or at least I would have been. I'm just so sick of it that I've pulled Cleat and I'm done with any more personal projects that use the Twitter API.

House of Lords - time for Legislative Service?

Updated on Thursday, November 12, 2015

House of Lords - time for Legislative Service?

I've mulled the idea of having an upper chamber randomly selected from the public like jury service for some time, often over a pint with a friend who prefers to remain nameless. This friend wrote an outstanding letter to Mark Harper which is included below by his kind permission. 

Mark Harper didn't manage more than a stock response, and neither did Matthew Offord and so it doesn't seem that the British Government is taking up the concept any time soon. We talked about the e-petition system but it turns out that it's limited to 1,000 characters and submissions are vetted for duplicates. There is an existing e-petition with this idea written by Simon Ferrigno which I've voted for, and if you support the legislative service idea please do the same.

Dear Mr Harper

We understand that you are working with the Deputy Prime Minister on the matter of an elected second chamber. We’re sure that many proposals and reports have crossed your desk on this topic. We’d like to share something we came up with when the issue was initially raised a few years ago. Having kept abreast of developments via media reports, we were both surprised not to hear anything similar mooted.

Our suggestion is that the second chamber be made up of ordinary members of the public drawn from across the country, randomly selected from the electoral roll, typically for up to 2 weeks of service. The system would be administered in a similar way to jury duty, albeit on a national basis. These people would be brought together, put up in decent accommodation, well fed, and otherwise made to feel as if their presence and contribution is both valued and important. They will be tutored, in an unbiased fashion, on the background of the Bill under their consideration. The syllabus could be defined by the civil servants who draw up the legislation under consideration. At this point, a multiple choice test on what they have been taught will be administered, but the results will not be revealed.

After the test, they will have the specifics of the Bill explained to them by two barristers (selected by parties for and against). The barristers will have the ability to bring in subject matter experts (perhaps drawing on the talent pool currently in place in the HOL). At the end of the evidentiary stage, the “constitutional jury” will have the opportunity to debate the issues and pose any further questions they may have to the barristers or witnesses.

Once completed, the constitutional jury will vote on the matter(s) at hand. The only votes that will actually count are those cast by people who passed the multiple choice test (as long as a quorum is reached). The results will only be reported as percentages. No one will ever be told if their vote counted, and all members of the constitutional jury are recorded as having served in deciding the matter.

Among the numerous advantages, as we see them, are:

  1. Politicians are often heard bemoaning the lack of public engagement with politics. This is an ideal way of re-engaging ordinary members of the public with the business of politics and what happens in Parliament.
  2. The primacy of the House of Commons will be ensured due to the transience of the members of the second chamber.
  3. There are no expensive elections to be paid for, nor will anyone’s voting record need to be skewed to ensure their re-election.
  4. As this chamber will be entirely made up of randomly selected members of the public, there can be no claims of cronyism.
  5. Voting along party political lines may be reduced; hence the decisions made are those that a random cross section of society deem to be right, rather than the whips.
  6. As the names of the constitutional jury are not disclosed until after the final voting, lobbying by vested interests will be reduced.
  7. The second chamber does not necessarily need to be based in London. In fact, there is no reason why it cannot become a travelling roadshow, convening on a rotating basis in major towns and cities around the UK. This may go some way towards quietening some of the accusations that Parliament is London-centric and lessening talk about the Westminster Village.
  8. Should Parliamentary time be short and the workload high, multiple constitutional juries can be assembled (perhaps in different locations), to work in parallel considering different Bills.

We realise that some members of the House of Lords serve on multiple select committees. We’ll admit to not having a plan for how these will be staffed in the future. One could assume that for now, they can be appointed by Parliament continuing to draw on the talent pool from the current HOL and augmenting any vacancies with new appointments proposed by a committee of civil servants.

We realise that all parties are currently wedded to the idea of an elected second chamber. Is there any way that this could work as a viable alternative?

Yours sincerely...
