I know MD5 is no longer secure, but is there an algorithm running in polynomial time to find preimages of a given hash, or is it just bruteforce?
Continue reading Is there a well-defined algorithm to find preimages in MD5?
In cryptography, generally we have two ways of handling sensitive information.
We can use one-way encryption such as hashing. This is useful when we never need to retrieve it again. In this case, we can know if we found the right password,… Continue reading Encryption Algorithm With Separate One-Way (Hashing) And Two-Way (Decryption) Keys
Take an example of AIDE (Advanced Intrusion Detection Environment), it has a capability to scan system file changes based on checksum.
So in AIDE you can see it has this kind of configuration setting in /etc/aide/aide.conf that we can set … Continue reading What is the purpose of using different hash algorithm to detect file changes [duplicate]
I’m working on a API which is serving content based on user requests. What I’d like to achieve is as follows: Having a constant key stored both on the server and the client machine (as a means of identifying a specific user) I’d like to be… Continue reading One-way cryptographic algorithm with distinct output and verifiable property
[Rostislav Persion] wrote a simple Morse Code decoder to run on his Arduino and display the text on an LCD shield. This is probably the simplest decoder possible, and thus …read more Continue reading Quick and Simple Morse Decoder
Many organizations are turning to artificial intelligence (AI) and machine learning (ML) to boost their cybersecurity systems, but you mostly hear about how AI is used to monitor networks and perform the time-consuming tasks that are overwhelming for … Continue reading Adding AI/ML to Mobile Security
The goal when creating or changing your password is to make it as unique as possible so that it cannot be easily guessed and hence compromised. The main goal of salts is to achieve this. They increase the uniqueness of your password on the… Continue reading How can we use salts to increase the efficiency of hashing? [closed]
Are there any advanced security technologies, for example, establishing a secured connection, which first require authentication based on security through organic-like changing obscurity of secrecy?
I’m not a fan of "regular" sec… Continue reading Security technologies that implements security through "organic-like" obscurity? [closed]
Need security tool for deniable encryption with requirement below:
use 1 passphrase only for encryption and decryption, without any key
given correct passphrase, it will be decrypted
given any incorrect passphrase, it will be decrypted … Continue reading Security Tool for Deniable Encryption [closed]
I am looking for tools / software / library / algorithm, that can shuffle private key, by using passphrase only, and then use the same passphrase to de-shuffle, but if it is wrong passphrase, then it will re-shuffle again, instead of de-sh… Continue reading Shuffle Tool / Software [closed]
