Your style. Fully tune your authentication experience without the effort.

We get it: authentication is one of the first boxes to check when building a website or application. It’s built to get the job done, and then it slowly becomes legacy code that no one wants to touch.
Today’s rapidly evolving security landscape, diverse and context-specific UX needs, and user privacy concerns all require more from traditional authentication. NuID addresses these challenges with a platform that grows and adapts to the new demands of digital identity.
By building with NuID, you ensure your applications and services remain embedded in modern cryptographic best practices.
Because that's what login should do.
Read the DocsThis software image is for Cisco's IOS XE software, which runs on their 4500E series switches. These switches are part of Cisco's line of enterprise networking equipment, known for their versatility and scalability in various network environments.
The "universal" in the filename is crucial for understanding how the software works. Unlike older IOS images where the feature set was fixed, a universal image contains all feature sets (LAN Base, IP Base, and IP Services) within a single binary file. The actual features available are determined by the license installed on the device, not the image itself. cat4500euniversalk9spa031105e1527e5bin hot

The 152-7.E5 component corresponds to the classic 15.2(7)E5 IOS version. This means that while the image runs on the IOS-XE architecture, the feature set and CLI behavior are based on IOS release 15.2(7)E. Understanding this mapping is crucial for compatibility, as the standard practice is to refer to the 03.11.05.E version—the 152-7.E5 component is derived from it and is not used for direct reference. Unlike older IOS images where the feature set
This release includes comprehensive IPv4 and IPv6 routing protocol support. This includes OSPFv2 and OSPFv3, EIGRP for IPv4 and IPv6, BGP-4 for service provider peering, and multicast routing with PIM-SM and SSM. The image also supports advanced features like MPLS for service provider deployments.
Provides granular Layer 3 routing topology management including full Open Shortest Path First (OSPFv2/v3), EIGRP, and BGP architectures.
This software release brings several significant improvements to the Catalyst 4500E platform:
At NuID's core is an established cryptographic method to verify that a user can produce a secret value, such as a password or private key, without revealing that secret to anyone. Ever.
Instead of sharing this secret with an authenticating server, a cryptographic zero knowledge proof of the secret is generated on the client device. The proof is used to verify that the user input the correct authentication secret, without any private authentication data leaving their device.
Combining this capability with emerging distributed ledger technologies removes the need for users to trust anyone with their passwords and other authentication secrets, giving them ownership over their authentication credentials and, eventually, their digital representation across the web.
NuID White Paper
We believe the next wave of technological transformation will bring persistent, privacy-forward digital identity to the web, which will simplify and de-risk the flow of information over our public and private networks.
NuID's open authentication protocol and API were designed to transition seamlessly between web2, web3, and all the webs before and after that. And authentication is only the beginning.
NuID is building a foundation for a decentralized identity ecosystem
that goes beyond just login. Check out the NuID White Paper to learn about the future of digital identity, or get in touch to discuss
with our team.
Users—people—want more privacy, transparency, and agency in how their online data is managed. In other words, we need to retrofit the internet with a sound identity layer.
