Encryption is a way of scrambling data so that only authorized parties can understand the information. In technical terms, it is the process of converting human-readable plaintext to incomprehensible text, also known as ciphertext. In simpler terms, encryption takes readable data and alters it so that it appears random. Encryption requires the use of a cryptographic key: a set of mathematical values that both the sender and the recipient of an encrypted message agree on.
The two main kinds of encryption are symmetric encryption and asymmetric encryption. Asymmetric encryption is also known as public key encryption.
In webuzo you can add asymmetric keys from Webuzo User Panel > Email > Encryption.
How encryption works
Public keys have been described by some as being like a business’ address on the web – it’s public and anyone can look it up and share it widely. In asymmetric encryption, public keys can be shared with everyone in the system. Once the sender has the public key, he uses it to encrypt his message.
Each public key comes paired with a unique private key. Think of a private key as akin to the key to the front door of a business where only you have a copy. This defines one of the main differences between the two types of keys. The private key ensures only you can get through the front door. In the case of encrypted messages, you use this private key to decrypt messages
Popup screen will appear to add details for keys.
Name : Add name for keys.
Email : Add email id for keys.
Comment or Nickname : you can add comment or nickname for the keys here.
Key Password : Set password for keys, it is recommended to use auto generate password for security purpose. it will generate strong password.
Expiration Date : Set expiry date for the key. if you set never expires it will not expire. to set keys for specific time duration you can set that by selecting days, weeks, months or years.
Key size : Select size for the key.
