There are several methods for encrypting data in transit, such as IPsec, SCP, SFTP, SSH, OpenPGP and HTTPS. Data in transit is data that is being sent over a computer network. Software which encrypts “data in transit”: These software usually use public key ciphers.Software encryption are into two categories: Symmetric key ciphers: A symmetric key is preferred to over the private and public keys because it uses less CPU cycles.Public key (Asymmetric) ciphers: This method uses two different keys, one to encrypt and the other to decrypt.Software encryption uses a cipher to obscure the content into cipher-text. We have already discussed the concepts of cryptography in detail in a separate post: Data Encryption. Encryption software is software that uses cryptography to prevent unauthorized access to digital information.
