I was thinking of using gpg4win to encrypt files I’ll upload to cloud storage services. I already use 7-zip so if I just wanted to password protect my files I could have easily done it, but I wanted to implement TLS style asymmetric encryp… Continue reading GPG4WIN Kleopatra does not require RSA secret key components to decrypt
I don’t why we can decrypt the message using our private key if it’s encrypted using our public key.
If a message is encrypted using my public key, then how can I decrypt it using my private key? It doesn’t make sense at all.
The only way … Continue reading decryption of message using private key [duplicate]
I am working on an application which has a requirement to send very small messages (<64 bits), asynchronously, and using secure asymmetric encryption. We’ve experimented with simple RSA + OAEP, and it is workable, but with the caveat th… Continue reading Asymmetric encryption of very small messages
I am preparing for the Sec+, currently reading the book, "Mike Meyers …. Certification Passport"(book in question is irrelevant to the problem), In the cryptography chapter, topic-public key/asymmetric cryptography
It says
I’m in the process of building a secure document storage on behalf of users of a web and mobile application. The goal is to have end-to-end encryption, as in documents will be encrypted and decrypted on device, but not require users to man… Continue reading How to manage a users private key in a secure document storage solution?
Using the cipher suite “TLS_AES_128_CCM_SHA256”
This example is referring to a self signed certificate
If a server uses TLS and uses the cipher suite above? How does the certificate get signed if there is not an asymmetric private key to s… Continue reading How does a Cipher Suite Work without an Asymmetric Algorithm?
Background information:
I have a client application that communicates with a server through a web API.
The data being communicated is not personally sensitive (no passwords, credit card details, usernames, etc). It’s just challenge/respons… Continue reading Benefit of asymmetric encryption vs trivial alternatives in compromised software?
I am trying to implement a cramer-shoup cryptosystem but I don’t understand how to work with the plaintext I want to encrypt.
From what I understand, the plaintext needs to be converted to an element of the cyclic group G, which was genera… Continue reading How to convert plaintext to element of cyclic group in Cramer-Shoup cryptosystem [migrated]
Do you know a good cryptography library for the Sipeed Longan Nano?
I need this algorithms/cryptosystems:
-sha2
-sha3
-argon2id
-aes256
-twofish
-chacha20
-McEliece Cryptosystem
-Curve25519
-Rabin
The library must not include all algorithm… Continue reading a good crypto library for the Sipeed Longan Nano [closed]
I am banging my head about this for a while now and would appreciate opinions/different views.
tl;dr
There is a system that aims to provide full end-to-end encryption for information (text messages, blobs) exchanged through it. At the mome… Continue reading Security vs. User Experience – can this Process still be considered to provide proper End-to-End-Encryption?
