Navigating the Let's Encrypt Transition: An MSP's Perspective

As the digital landscape evolves, so too must the infrastructure that supports it. This sentiment holds especially true for Let’s Encrypt, the widely trusted provider of SSL certificates. In a recent announcement, Let’s Encrypt detailed its plans to shorten the chain of trust, marking a significant milestone in its journey towards enhanced security and efficiency.
At Crafty Penguins we understand the importance of staying ahead of such transitions to ensure seamless operations for our clients. In this blog post, we’ll delve into Let’s Encrypt’s decision and outline the implications for businesses and organizations relying on SSL certificates for secure communication.

Understanding the Transition
Let’s Encrypt’s journey began with a cross-signing arrangement with IdenTrust’s DST Root CA X3 to establish trust for its certificates. Over time, Let’s Encrypt’s own ISRG Root X1 gained widespread recognition, reducing the reliance on cross-signed intermediates.
However, as technological landscapes shift, so too do the requirements for maintaining trust across platforms. With a significant portion of Android devices still running older OS versions, Let’s Encrypt opted for a stopgap measure to ensure continued compatibility. This interim solution allowed for uninterrupted trust while accommodating legacy systems.

The Path Forward
Fast forward to 2024, Let’s Encrypt is poised to take the next step in its evolution by phasing out the cross-signed chain entirely. This decision is not only driven by the increasing adoption of newer Android versions but also by the need to streamline operations and reduce overhead costs.
For businesses and organizations utilizing Let’s Encrypt certificates, this transition calls for proactive measures to ensure uninterrupted service. Let’s break down the timeline:

• February 8th, 2024: Let’s Encrypt ceased providing the cross-sign by default, signaling the shift towards the shorter certificate chain.
• June 6th, 2024: The longer cross-signed chain will no longer be available, allowing for a sufficient migration period.
• September 30th, 2024: The cross-signed certificate will expire, marking the completion of the transition.

Implications for Businesses
For businesses and site operators, it’s crucial to monitor website usage statistics and user-agent strings during the transition period. Any sudden drop in visits from Android devices may indicate the need to advise users on updating their browsers or utilizing alternative solutions, such as Firefox Mobile.
Additionally, ACME client authors must ensure their clients are configured to download and install the certificate chain provided by Let’s Encrypt’s API correctly. This ensures seamless certificate issuance and renewal processes without risking trust issues.

Partnering for Success

We extend our appreciation to IdenTrust for their partnership and contributions to Let’s Encrypt’s journey. Their commitment to creating a secure web ecosystem has been invaluable, and we look forward to continued collaboration within the cybersecurity community.
In conclusion, Let’s Encrypt’s decision to shorten the chain of trust marks a significant milestone in its quest to provide secure communication for all web users.
