Secure Hash Algorithm 1 (SHA-1) Circumvented by Google
Around 2 years back we talk about how to upgrade to SHA-256 and ECC SSL (ECDSA) certificate for the TLS/SSL certificate users. Secure Hash Algorithm 1 is a Cryptographic hashing function. Secure Hash Algorithm 1 (SHA-1) is Circumvented by Google Research For Testing Vulnerability. Some researchers theorised vulnerabilities of SHA-1 from 2005 and now have been exploited for the first time with an … [Read more...]
How To Create Own 3D Model From Photograph
3D is not a craze but a need. 3D Printing is the future. There are services which charges huge for 3D printing mini replica. However, we can devote a time to slowly create own or wanted closer people's 3D replica and print it. After printing we can paint it. If we do not have 3D printer, there are 3D printing services. There is no easy way to create 3D replica from photograph. Here is a guide on … [Read more...]

Cloud Server Monitoring With Glances
There are definite planing differences between monitoring dedicated server and cloud server. One of them is that - components and sensors are not physical. Another point is that 6GB RAM OpenVZ server instance costs $7/month, whereas a 32 GB RAM dedicated server costs not exactly lesser with good networking. So, slight more RAM consumption is not very bad in case of a cloud server. Glances is a … [Read more...]
