| | | | | Here at Trail of Bits we review a lot of code. From major open source projects to exciting new proprietary software, we've seen it all. But one common denominator in all of these systems is that for some inexplicable reason people still seem to think RSA is a good cryptosystem to use. Let me save [...] | |

| | | | | Motivation RSA (Rivest-Shamir-Adleman) is one of the first public-key cryptosystems and is widely used for secure data transmission. In such a cryptosystem, the encryption key is public and is different from the decryption key which is kept secret. If I wanted to comprehend zero knowledge proofs, then understanding the grand-daddy of public-key cryptosystems is a must. Background Maths Exponential Rules 1 $$ \begin{align} \label{eq:exponent_rule} g^{a-b} &= \dfrac{g^a}{g^b} \newline g^{a+b} &= g^a g^b \n... | |

| | | Some users asked me about a Gizmodo article that claims everybody should stop using Telegram because we don't encrypt chats. Unfortunately, this article is based on incorrect and misleading statements. 1. Always encrypted The author confuses encryption and end-to-end encryption and claims that some data on Telegram is sent and stored unencrypted. This is not true. All data is encrypted. Secret Chats use end-to-end encryption, Cloud Chats use server-client encryption in transit and are of course encrypted in... | ||
