When one is transferring files containing sensitive information, it is important to ensure that the data is enciphered and not accessible to intrusive eyes, whether the file is stationary or in the process of transfer. A definite way of securing files prior to, at the time of, and after transfer is through PGP (Pretty Good Privacy) file encryption. The PGP system for encrypting and decrypting data employs a public key solution. In the PGP system, the original creator of the file shares the key with the intended recipient to encrypt the file, and then employs the private key to decrypt the contents of the file.
Let’s consider five fundamental factors when using PGP:
- Do not let PGP hinder daily business processes. Possibly, one business house might want to assert its present procedures involving PGP or needs to extend patronising PGP because its preferred business partners use it. Regardless of how PGP is being employed as part of the data transfer procedure, it is critical to ensure that the entire process does not get hindered or bogged down due to the signing, encrypting, decrypting and key-exchange phases.
- Making PGP effortless and Easy to Use. A number of PGP libraries – and its affiliated encryption/decryption procedures – are command-line managed. Therefore, it can sometimes become tiresomely long to employ PGP. However, some systems permit one to control PGP from a from a graphical user interface, which can be a highly advantageous alternative for most companies and users who are looking to govern the procedure.
- Ascertain the ability to exchange and use information in a large heterogeneous network. Every company wants to ensure that it can effortlessly and steadfastly share digital data with its preferred partners or clients. In order to do that, the company must not only need to sustain their encryption process of choice, but also all likely encryption libraries. One such option is the OpenPGP file encryption benchmark that is useful in enabling interoperability within most libraries, and is the favoured choice at present, for PGP. Hence it is vital that companies seek a solution that supports the ability to exchange and make use of information from different computer systems.
- PGP is unforced and voluntary. Some companies that choose managed file transfer often opt to exclude PGP encryption from the equation since they believe that their data is being fortified at the transport layer. Even so, it is important to note that the solution employed by the company is utilising the most reinforced and robust possible SSL or TLS cryptograph during data transmission.
- Prevent intentional and accidental file manipulation. Part of guaranteeing that digital files are safely transmitted is to be able to authenticate that the transmitted files have not been endangered in in any case either prior to, at the time of, or after transmission. Integrity checking makes use of hashing to confirm and authenticate that the digital contents sent from the origin is the very same file obtained by the intended recipient. Otherwise stated, it appropriates one to substantiate that the file’s messages have not been altered within the time it was transmitted and obtained – or throughout its ensuing storage.
Any organisation can perform integrity checking while employing PGP when the sender digitally signs the digital file. Business houses need to look for a solution that lets it record all its authentication integrity-scrutinising specifications in order to have a record of the file updating that takes place during a specific transaction.
