Introduction to Putty version
Putty is an application that will help to get the remote session of the UNIX or the Windows platforms. It is written by Simon Tatham. The latest version of the putty is 0.76. When we are working with Linux machines, we are using SSH communication. The SSH stands for the Secure Shell. It is a network communication protocol; it will help to establish the session with the Linux machines. While working with the putty, we need to consider the rules and the legal warnings. If we are using the PSCP, Plink, PSFTP, and Putty, we need to make sure that those countries not following the encryption or the encryption are illegal. In those countries, the PSCP, Plink, PSFTP, and Putty application is illegal. There are lots of countries that support encryption. They also believe in the legal use of the PSCP, Plink, PSFTP, and Putty application. Those countries are Wales, England, and many more. If we have any doubt in terms of the legal term, we need to check the terms or conditions or legal advice information. It is good practice that before downloading an application, we need to go through with the legal terms. You will get more or useful information on the cryptolaw.org page. Here, it is having the cryptography laws information in different countries.
Versions of Putty
We need to select the proper or appropriate version of the putty application. It will help to overcome connection or communication bug-related problems. Generally, it is recommended that we need to choose or use the latest version of the software or application. Because the latest version will remove the older bug and will be compatible with the latest technologies. But in some cases, we need to use the specific version of the putty. Because the application or the job needs some special configuration or dependant that should suffice in the older or the specific version. Before directly going on the putty version, first, we need to understand how the putty application will be able to connect with the Linux machine. It will help to understand more about the version, and if any issues may occur, we can fix such types of issues. If we need to connect to the Linux machine, we will use SSH communication. It is nothing but a secure communication network protocol. It is running on port no 22. The default port for the SSH is 22 only. In terms of security, if we need to change the SSH port, we can also change the SSH port. In any version, we need to add the Linux machine hostname or the IP address along with SSH port no. Once the connection is established, we need to add the user name and password. In the second method, we need to use the PPK file to access the Linux machine. It is one more secure way to access the Linux machine. In some cases, the PPK file is not present; we need to select the PEM file. Here, we need to use the puttygen application to convert the PEM file to the PPK file.
1. Putty Version 0.76
As per the current information, we are on the latest version of the putty, i.e., the version 0.76. But the pre-release build version of the putty 0.76 is available. So it will be really great if more or a number of people will use the same version, and if any issues of bugs will come then, it should be the highlight.
In the putty version 0.76, it has fixed the high impact level bugs. It has appeared in the version 0.75. There are few crash-related issues also. Generally, it happened when we have enabled the system colors option or the setting in the windows putty. In some cases, there are few DNS-related issues, like DNS blocker, due to which we cannot download the version. In some cases, if we are using the public Cloudflare DNS like 220.127.116.11 or 18.104.22.168, then we are getting the putty download issues. If you are facing issues while downloading the latest version of the putty, then we need to check the DNS setting of the working machine.
2. Putty Version 0.75
In the putty version 0.75, the major work is on the SSH private key files and SSH key fingerprints. Few new network protocols also come into the picture. In the windows terminal emulator, the version 0.75 is having the DoS vulnerability. Due to which it is granted the lock the windows GUI application. In version 0.75, there are lots of challenges like the SSH public keys, etc. Here we are working on the SHA-256, a different OpenSSH style. In the putty version 0.75, we added the support-related parts, like the rsa-sha2-256 and the rsa-sha2-512 signature parts. Some servers or the communication medium will require using the RSA keys. For the private key files, we have announced the new format of the PPK file. We have removed the crypto dependency.
3. Putty Version 0.74
In the putty version 0.74, it is come up with the bug fixes and the security release. It is fixes bugs in version 0.73. It has included one possible vulnerability. It has also been added to the new configuration parameters also. It is overcome the information leak issue in the SSH and over from this issue. The issues related to the host key policy.
4. Putty Version 0.73
In version 0.73, as per the hierarchy, it has fixed the bugs in version 0.72. But in this version, the multiple security issues were fixed.
