I’ve been reading about how clients can verify JWT signatures using a public key provided by the server. I’m struggling to understand how this solves any issues.
The only attack I’ve seen which this claims to solve is when a reverse proxy … Continue reading How is client side JWT signature validation beneficial from a security perspective?
I read this, but it doesn’t say if the public keys of the root and intermediaries are inside.
I understand I need to upload my digital certificate that I obtained from CA and also my private key. But what happens in the server after I uploaded? Does the server actually read my certificate and sign a message taken from the cert and … Continue reading What happens behind the scene when I install an SSL certificate for a website?
I used the following command to sign and encrypt my file symmetrically. The secret and public keys for the user PG are available locally and were generated on the same machine (say Machine A).
gpg -v –sign –symmetric –no-symkey-cache –… Continue reading GNU – Verify and Decrypt a symmetrically encrypted file [closed]
Use of digital certificate for signing the files which are auto-generated by the applications that belong to a sister-concern entity that is into products/services to the other sister-concern entity which is into Finance.
Is this something… Continue reading Digital signing of invoices when exchanged between entities [closed]
I would like to understand how certificate-based signature works, I understand the standard asymmetric key signature where one party signs using their private key, and anyone else can validate this is authentic by checking against the publ… Continue reading How does a CA-backed signature works?
We have 2 servers communicating, server A (a server that I own), and server B (server on the internet that I trust). I get some info from server B, which are FIX messages (https://en.wikipedia.org/wiki/Financial_Information_eXchange).
Serv… Continue reading Using FIX over TLS, is there a need to sign FIX mesages?
The /INTEGRITYCHECK linker option sets a flag that "tells the memory manager to check for a digital signature in order to load the image in Windows". So the general idea is that this ensures the binary is signed by a legitimate,… Continue reading What protection does the /INTEGRITYCHECK MSVC linker option offer, if a malicious file without it can simply be substituted for the authentic file?
I have 2 endpoints that are exchanging data (FIX messages), and the originating endpoint is genrating the fix files are sending them on an ecrypted channel (TLS or Stunnel). In a security audit, it was recommended that the files are signed… Continue reading are files sent in a TLS channel signed? [duplicate]
I’m developing a website and trying to use the algorithm RS256 to generate and verify the signatures of clients (JWT).
Here is how I generate a signature at the client side (I use the Python script to simulate a client):
header = {
&qu… Continue reading How does RS256 work in a website
