Encryption. In cryptography, encryption is the process of transforming (more specifically, encoding) information in a way that, ideally, only authorized parties can decode. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Despite its goal, encryption does not ...
The encrypting procedure is varied depending on the key, which changes the detailed operation of the algorithm. A key must be selected before using a cipher to encrypt a message. Without knowledge of the key, it should be extremely difficult, if not impossible, to decrypt the resulting ciphertext into readable plaintext.
Email encryption is encryption of email messages to protect the content from being read by entities other than the intended recipients. Email encryption may also include authentication. Email is prone to the disclosure of information. Most emails are encrypted during transmission, but they are stored in clear text, making them readable by third ...
At AOL, we make every effort to keep your personal information totally secure. SSL (Secure Sockets Layer) is an industry standard for encrypting private data sent over the Internet. It helps protect your account from hackers and insures the security of private data sent over the Internet, like credit cards and passwords.
Before the modern era, cryptography focused on message confidentiality (i.e., encryption)—conversion of messages from a comprehensible form into an incomprehensible one and back again at the other end, rendering it unreadable by interceptors or eavesdroppers without secret knowledge (namely the key needed for decryption of that message).
To use the Vigenère square to encrypt a message, a coder first chooses a keyword to use and then repeats it until it is the same length as the message to be encoded. If LEMON is the keyword, each letter of the repeated keyword will tell what cipher (what row) to use for each letter of the message to be coded. The cipher alphabet on the second ...
Let be the plaintext message that Alice wants to secretly transmit to Sonny and let be the encryption cipher, where is a cryptographic key.Alice must first transform the plaintext into ciphertext, , in order to securely send the message to Sonny which first would need access to certain tools along with a secured network that is not traceable, but rather leaving a trace to a deadened is better ...
Decrypt a message only intended for the recipient, which may be encrypted by anyone having the public key (asymmetric encrypted transport). Encrypt a message which may be decrypted by anyone, but which can only be encrypted by one person; this provides a digital signature.
