Encryption

Encryption.

Encryption is the translation of data into a secret code. Encryption is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it.

There are many advantages to encrypting files:

• ·         Encrypted files by one user cannot be opened by another user if the latter does not possess appropriate permissions.
• ·         The user with permission to decrypt a file is able to work with the file like with any other, without experiencing any restrictions or difficulties.
• ·         Other users receive a restricted access notification when they attempt to access the encrypted file.

But there are also disadvantages to encrypting files:

• ·         If you forget your passphrase and/or keyfile then there is almost no chance of recovering your data.
• ·        The very existence of encryption programs or encrypted files will attract suspicion as to what it is you are trying to protect whereas a non-encrypted system would not attract the same level of interest.
