poc-cve-2016-10555

Change the algorithm RS256asymmetric to HS256symmetric - POC CVE-2016-10555 The algorithm HS256 uses the secret key to sign and verify each message. The algorithm RS256 uses the private key to sign the message and uses the public key for authentication. If you change the algorithm from RS256 to...

CVE-2026-35088 Inadequate Encryption Strength in Slican telephone exchanges

Slican telephone exchanges use symmetric encryption for TCP/IP communication. Secret key is hardcoded in multiple binary files. An attacker who has access to these files can decrypt the communication. This issue was fixed in IPx series version 6.62.0100. The issue STILL EXISTS in End-Of-Life...

CVE-2026-35088

Slican telephone exchanges are vulnerable to a security flaw where symmetric encryption keys for TCP/IP communication are hardcoded within multiple binary files. An attacker with access to these files can decrypt the communication. This issue was resolved in IPx series version 6.62.0100 . However...

The Future of AI Cryptanalysis

Matthew Green has been writing a rather pessimistic series of posts about the potential for AI systems to vastly outperform humans in cryptanalysis of both symmetric and public-key ciphers. I am more optimistic than he is. That is, I have stronger faith in the over-engineering cryptographers tend...

CVE-2026-102268

A flaw was found in PyJWT. When an application allows both symmetric and asymmetric signing algorithms, minor formatting variations in a public key can prevent the library from properly identifying it as an asymmetric key. Consequently, the library improperly treats the public key as a shared...
