I am solving a lab related to serialization vulnerabilities. It deals with retrieving files based on the signature. The theory of the lab states as quoted, "Adding ./ will still give you the same file but the application will generate… Continue reading How does "./" affects signature generation for files, in a PHP based web application?
My company is looking to allow Google Chrome to self-update, a necessity as we are finding it difficult to keep up with their release cycle in order to mitigate vulnerabilities.
On the pro side, letting the software auto-update helps us re… Continue reading Does Google Update perform cryptographic checks against releases?

I’m curious to know how mTLS works in more detail in regard to client authentication.
Firstly, I issued 3 certificates: root CA, server and client. The last two are signed with the root CA.
Secondly, I imported the client’s .p12 (the clien… Continue reading Role of public and private keys of client certificate in mTLS [duplicate]
Are there any guidelines for making use of attached signatures and detached/embedded signatures?
What are the pros and cons of these approaches and what are the selection criteria?

We are looking for a solution to meet the needs of a UK incorporated charity (CIO) that has three to seven trustees from at least three continents.
Obligations as trustees of a board include signing (by a quorum of the trustees):
Are there any guidelines for making use of attached signature and detached signatures? Are both of these governed by IETF standards?
What are the pros and cons of these two formats?
I came across enveloping signature and enveloped signatur… Continue reading signing of software/firmware for authenticity and integrity checks [closed]
I have created an App and made clients install it on there phone.
When my app tries to connect to server or request data from my server I want to verify if that app is genuinely my app and not modified or tempered version of my app, Can an… Continue reading Is there any way I can verify that my app in not modified or tempered (code is changed or something) on clients phone?

When verifying a pgp signed message using GnuPG, one gets an output similar to the following:
gpg: Signature made Fr 07 Jan 2022 13:42:21 CET
gpg: using RSA key 610B4AFF906E6890EEDC797201E99CB6C034BC3B
gpg: is… Continue reading Exact meaning of RSA key in `gpg –verify` output
I am quite confused about the security definition of blind signature schemes in the concurrent setting. I have found a paper as follows showing that most of the previous blind signature schemes cannot satisfy unforgeability property if the… Continue reading Security of Blind Signature Schemes in the Concurrent Setting
