TREAT AS URGENT!

by Principal Consultant

Dear sir/Madam, The Foundation is in the process of making significant investments—ranging from $1 million to $100 million—in individuals, organizations, and corporate entities that demonstrate strong potential to create meaningful, long-term impact. As part of this initiative, you have been selected for consideration for a funding allocation between $3 million and $10 million. This funding is specifically intended to support community-based projects that address the needs of underserved populations, while also ensuring that you and your family have the stability and resources necessary to sustain this work. The minimum amount approved is $3 million, and the Foundation has established a clear structure for how these funds may be used: 60% of the funds will be dedicated to project-related expenses, including program development, operations, staffing, and other costs directly tied to serving the community. 40% of the funds will be allocated for family support, recognizing that personal stability is essential for long-term leadership, focus, and success in carrying out these initiatives. Should a higher funding amount be approved (up to $10 million), this same purpose-driven framework will apply, with allocations scaled accordingly. This investment reflects the Foundation’s commitment not only to impactful community outcomes, but also to supporting the individuals leading this work in a sustainable and holistic way. We hope to hear from you soon. Best regards, --- Evans - Principal Consultant - PIF-(FDI-SPV). Tel/Whats-app:+ (44) 7466 557915.

Mbed TLS 4.0.0-beta & TF-PSA-Crypto 1.0.0-beta

by Minos Galanakis

I am happy to announce the joint-release of Mbed TLS 4.0.0-beta & TF-PSA-Crypto 1.0.0-beta PSA-Crypto now lives in its own repository while TLS and X.509 remain in Mbed TLS. This beta release breaks compatibility with earlier versions of Mbed TLS. Please do not use it in production. It’s intended for the community to verify codebase integrations against the split and API changes, and for early adopters to experiment and provide feedback.

Announcing Mbed TLS 3.6.3 and 2.28.10

by Gilles Peskine

Dear Mbed TLS users, The next release of Mbed TLS (3.6.3 and 2.28.10) is scheduled on Monday 2025-03-24. It will include a security fix for a vulnerability with a high impact to affected applications. Due to the nature of the vulnerability, which involves an insecure default in current versions of Mbed TLS, fixing it may require a small change in application code. We will provide instructions in the release notes. Without this change, affected applications will fail at runtime with Mbed TLS 3.6.3 or 2.28.10. Applications that are currently secure will generally not require any change. We apologize for the inconvenience. Best regards, -- Gilles Peskine On behalf of the Mbed TLS security team IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged. If you are not the intended recipient, please notify the sender immediately and do not disclose the contents to any other person, use it for any purpose, or store or copy the information in any medium.

Mbed TLS 4.0/TF-PSA Crypto 1.0 release timeline

by Janos Follath

Dear Mbed TLS and PSA Crypto users, We would like to update you on the release timeline for Mbed TLS 4.0/TF-PSACrypto1.0 release. As a reminder, the key objectives of the release are a separate TF-PSA Crypto repo., PSA Crypto becoming the de facto Crypto API and Mbed TLS using PSA Crypto APIs as the crypto API by default. While TF-PSA Crypto repository is now available, the remaining effort to be ready for the release is more than we originally planned for. Based on remaining effort estimates, we plan to make Mbed TLS 4.0-Beta and TF-PSA Crypto 1.0-Beta release around end of June. The Mbed TLS 4.0, and TF-PSA Crypto 1.0 release is expected around end of September. We don’t expect users to integrate the Beta release. Beta is aimed to pipeclean the separate Mbed TLS and TF-PSA Crypto release process and get any early feedback. The release in September is expected to be integrated by users to their projects. We wanted to provide these revised release dates so that the users can plan accordingly. In the meantime, bug fixes and security fixes will continue to be provided via. Mbed TLS 3.6.x LTS releases. Thanks, Mbed TLS/PSA Crypto Maintainers.
