Learn and explore
TLS fingerprinting resources.
Understand the connection signals behind software identification, inspect public fingerprint formats, and explore Byteprint’s product direction.
Understand the fundamentals
What does a TLS handshake reveal? How does it differ from an HTTP User-Agent? Why can a proxy change which client you observe? Start with the concepts and interpretation limits.
Read the TLS fingerprinting guide →Work with the public JA4 format
Inspect a standard JA4 value in the local decoder, or compare the established JA3 and JA4 approaches. These educational resources cover public formats.
Read the JA3 vs JA4 guide →How does this relate to Byteprint?
Byteprint is developing its own TLS fingerprinting representation and software reference database. The public-format resources do not describe our implementation or establish format compatibility. The API overview is conceptual; access and technical specifications will follow through the private beta.
