**This is a ticketed event. Please register at [this link](https://luma.com/wbpv7ouu).** In this talk, Talha Paracha will present insights from his latest research on using language models for improving software security ("Hallucinating Certificates", to appear at ICSE 2026). Certificate validation is a crucial step in Transport Layer Security (TLS), the de facto standard network security protocol. Prior research has shown that differentially testing TLS implementations with synthetic certificates can reveal critical security issues, such as accidentally accepting untrusted certificates. Paracha et al. introduce a new approach, MLCerts, to generate synthetic certificates that leverages generative language models to more extensively test software implementations. Recently, these models have become (in)famous for their applications in generating content, writing code, and conversing with users, as well as for "hallucinating" syntactically correct yet semantically nonsensical output. The authors leverage two novel insights in their work: (a) TLS certificates can be expressed in natural-like language, namely in the X.509 standard that aids human readability, and (b) differential testing can benefit from hallucinated malformed test cases. MLCerts finds significantly more distinct discrepancies between the five TLS implementations OpenSSL, LibreSSL, GnuTLS, MbedTLS, and MatrixSSL than the state-of-the-art benchmark Transcert. ​​​**Event Schedule** 6:00 to 6:30 - Food and introductions 6:30 to 7:30 - Presentation and Q&A 7:30 to 9:00 - Open Discussions ​​​​​​If you can't make it in person, feel free to join the live stream starting at 6:30 pm, via [this link](https://www.youtube.com/@Trajectory-Labs/live).

## Rehearsal Details: Thursday evenings 6:30 p.m. to 9:00 p.m, Earl Bales Community Centre 4169 Bathurst St., just south of Sheppard, in Toronto. Email our membership chair, if you are interested in attending a rehearsal. **Lisa Taylor: 647-886-1766, [membershipchair@torontoaccolades.com](mailto:membershipchair@torontoaccolades.com)** Do you love to sing? Do you love performing for live audiences? The Toronto Accolades Chorus brings women-centric singers together to sing and perform a cappella harmony. Harmony connects people from all backgrounds, ages, and musical abilities to create a community where you can not only sing, but find a space to connect with other strong and dedicated people just like you. For decades, we've provided a venue for singers to express themselves, make quality music together, and form bonds beyond measure, and we invite you to join us for the ride. We welcome guests and work with them to find out their voice range and to determine what part (lead, tenor, baritone or bass) they would sing best. Guests are given a music folder and encouraged to participate in singing with the chorus in subsequent weeks. Although we continually strive for musical excellence, prior musical training is not necessary to belong to our chorus. We provide everyone with sheet music, audio learning tracks, education and guidance. At the end of 6 weeks, we ask each prospective member to audition, to ensure that they can hold their part in a four-part harmony song.

Jimmy V's Grill & Pub in Grandview Heights. We meet in the bar in the room on the right (the cigar shop). You are responsible for your own meal/drinks. We usually don't have any agenda other than eat, drink and talk. :) If the weather is nice we will be on the back patio, otherwise we are in the cigar room. This group has been meeting every Tuesday evening for over a decade. Many attendees do not RSVP on meetup. Please don't let the small number here discourage you. Anyone/everyone is welcome to come. We'd love to have you join us. COTA bus #5 comes to W. 5th and Wyandotte Rd. And it's a minute walk to the restaurant. *** Did you know that there are atheists everywhere?!?! You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'! Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life. Mission: grow, support, and provide community for atheists in Central Ohio. Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists. All attendees are welcome but should support our vision. Atheists of Columbus (AoC) is part of Omnipresent Atheists (OA). AoC members are invited to join this OA meetup and/or OA Facebook group ( https://www.facebook.com/groups/omnipresentatheists/ ) but are free to continue conversations on the AoC Facebook group ( https://www.facebook.com/groups/columbusatheists/ ). AoC was founded in 2012 as a networking, social group for Central Ohio area humanists, skeptics, atheists, agnostics, nonbelievers, freethinkers, and the curious. It was a member of Columbus CoR and held weekly meetings, mostly on Fridays, for several years but then operated as an online only group for some time. In November 2018, Omnipresent Atheists (OA), a group that routinely meets on Tuesdays, invited AoC to merge. Omnipresent Atheists is a member of the Columbus Coalition of Reason (ColumbusCoR.org). Omnipresent Atheists is a member of the Columbus Coalition of Reason ( http://www.ColumbusCoR.org ). Omnipresent Atheists endorses the mission of the Secular Coalition for America ( http://secular.org ).
