Encryption Tutorial
This very brief tutorial is for beginners, who have not used encryption tools before.
Introduction
There are two types of encryption methods, symmetric and asymmetric.
1) Symmetrical Encryption - The same password (or key) is used to encrypt and decrypt the data (file). This method is useful to encrypt sensitive information for you own use, or for use by family, or a few trusted friends/coworkers.
2) Asymmetrical Encryption - A public key file is used to encrypt the data. The corresponding private key file is used to decrypt the data. Only you should have access to your private key. You can distribute your public key to anyone who needs to send you data.
Password Based Encryption
This is the simplest form of encryption. It is a symmetrical encryption method. The same password is used to encrypt and decrypt the file.
Secret Key Based Encryption
This is the simplest form of key based encryption. It is a symmetrical encryption method. The same secret key file is used to encrypt and decrypt the data.
