@kelalaka Vreemd dat ze zowel RSA als ECDSA supporten, dat betekend 2 certificaten.

China's Great Firewall "is now blocking HTTPS connections set up via the new TLS 1.3 encryption protocol and which use ESNI

@kelalaka Sorry, I was reading a Dutch text (not Frisian, that's a separate language). Strange that they support both RSA and ECDSA because that means that they use multiple certificates.

kelalaka

I predicted it is Dutch, however, Google translate said it is Frisian.

Is there a problem with multiple certificates?

Maarten Bodewes

No, there isn't but generally you don't need two. I guess some software only uses RSA or something similar.

kelalaka

I think you are right.

Public key Algorithm
Elliptic Curve

Signature Algorithm
SHA-256 with RSA Encryption

Q: Can you crack this multiple-shift cipher?

The below is the cipher that is to be cracked : 40 77 77 60 6b 6e 29 69 73 19 6b 69 75 6d 2f 29 67 30 7c 73 75 6e 75 2c 70 20 74 26 74 68 6b 6c 70 67 66 27 66 28 69 5e 27 7a 68 63 6b 82 27 29 28 -de Need-to-know: -de is a termination character and is not part of the message. this ciphertext is ...
