The risk of losing data is an issue when working with Excel sheets and learning their shortcuts. Using the CONCATENATE technique is one approach to combining cells without losing data.
[mai mult...]Weak RSA decryption with Chinese-remainder theorem
RSA decryption is slower than encryption because while doing decryption, private key parameter ” d ” is necessarily large. Moreover the parameters – ” p and q ” are two very large Prime Numbers. Given integers c, e, p and q, find m such that c = pow(m, e) mod (p * q) (RSA decryption for weak integers).
[mai mult...]One Time Password (OTP) algorithm in Cryptography
The OTP is a numeric code that is randomly and uniquely generated during each authentication event. This adds an additional layer of security, as the password generated is fresh set of digits each time an authentication is attempted and it offers the quality of being unpredictable for the next created session.
The two main methods for delivery of the OTP is:
- SMS Based: This is quite straightforward. It is the standard procedure for delivering the OTP via a text message after regular authentication is successful. Here, the OTP is generated on the server side and delivered to the authenticator via text message. It is the most common method of OTP delivery that is encountered across services.
- Application Based: This method of OTP generation is done on the user side using a specific smartphone application that scans a QR code on the screen. The application is responsible for the unique OTP digits. This reduces wait time for the OTP as well as reduces security risk as compared to the SMS based delivery.

How to install, configure and use GIT on Ubuntu?
Git is a distributed revision control system with an emphasis on speed, data integrity, and support for distributed non-linear workflows. Every Git working directory is a full-fledged repository with complete history and full version-tracking capabilities, independent of network access or a central server. GitHub is a Web-based Git repository hosting service, which offers all of the distributed revision control.
