A crypt is a code. Encrypt means encode and decrypt means decode. In regards to your computer or internet usage, cryptography happens in the background. Information is encoded so others can't read it if they steal or find your computer, or if they intercept your information while it is on it's way to it's destination on the internet.
Windows only encrypts your drive if you set it up to do so. If you do, the "key," which is what is used to make and decode the encrypted data, is your password. If you forget the password, everything on your computer is lost, forever. If you give others the password, everyone can decrypt and view the data.
More important than encrypting your drive is data encryption. You should always use a secure wireless connection (one with a password) because this is the only way data is not visible to everyone on the network. (Don't believe this? Google "Firesheep.") If you are accessing your bank or paying online with checking account or credit or debit card, ensure you have a secure, encrypted, connection by looking to see that your browser says https:// before the url, NOT http://.
How data encrypt and decrypt from PC to PC using micro controller?
decrypt, encrypt
Private Key
The command 'cipher' calls a program that is integrated with Windows that can encrypt-decrypt files.
For some time it has been common practice to protect and tansport a key for DES encryption with triple-DES (3DES). The function follows an encrypt-decrypt-encrypt (EDE) sequence. Decrypt sequence is simply the same (encrypt) operation with the keys reversed.
Yes
The meaning of asymmetric encryption is that one key that is unique to a recipient is used only to decrypt data instead of a key being used to encrypt and decrypt that data.
The usual reason would be to encrypt and decrypt code
To encrypt a folder or fileRight-click the folder or file you want to encrypt, and then click Properties.Click the General tab, and then click Advanced.Select the Encrypt contents to secure data check box, click OK, and then click OK again.
It is an encryption process that uses a public and private key pair to encrypt/decrypt data.
Store encryption keys that can be used to encrypt and decrypt secondary storage areas like the hard disk
The Enigma machine was used during World War II to encrypt and decrypt secret messages by using a series of rotors to scramble the letters of the message. The machine had a different setting each day, known only to the sender and receiver, making it difficult for enemies to decipher the messages.
