![]() ![]() I encrypt it using one of the programs listed below. Say I want to send you a private message. Hider 2 vs encrypto apps software#Here's an example of how encryption works with email-friendly software Pretty Good Privacy (PGP) or GnuPG-also known as GPG-for open-source aficionados. The private and public keys are mathematically tied together, so the corresponding private key can only decrypt that information encrypted using the public key. One key remains secret-the private key-while the other key is made widely available to anyone who needs it. Asymmetric Key SystemsĪn asymmetric key system, also known as a public/private key system, uses two keys. While it's possible for this to work, securely distributing the keys to ensure proper controls are in place makes symmetric encryption impractical for widespread commercial use. Keys that encrypt and decrypt messages must also remain secret to ensure privacy. In a symmetric key system, everyone accessing the data has the same key. There are two kinds of cryptographic key systems, symmetric, and asymmetric. Typical key lengths are 128 and 256 bits for private keys and 2048 for public keys. Each key is unique, and longer keys are harder to break. The key length, functionality, and features of the encryption system in use determine the effectiveness of the encryption.ĭecryption is the process of converting unreadable ciphertext to readable information.Īn encryption key is a randomized string of bits used to encrypt and decrypt data. Here are some essential encryption terms you should know:Īlso known as a cipher, algorithms are the rules or instructions for the encryption process. ![]() Any unauthorized access to the data will only see a chaotic array of bytes. Encryption ensures that information stays private and confidential, whether it's being stored or in transit. Encryption uses complex algorithms to scramble data and decrypts the same data using a key provided by the message sender. How Encryption WorksĮncryption is a way for data-messages or files-to be made unreadable, ensuring that only an authorized person can access that data. ![]() While there are plenty of technologies you can buy to secure your data, encryption is one aspect of security technology that every computer user should understand. It must be, given that Gartner estimates that spending on information security and risk management will total $172 billion in 2022, up from $155 billion in 2021. Security is top of mind for anyone in IT these days. ![]()
