1. A cipher is an algorithm that encodes or encrypts data. Text that is "ciphered" (processed with a cipher, encrypted) cannot be read unless the original algorithm is known or reasoned out. In cryptographic ciphers, a special password or key must be provided to the decryption algorithm ...
Bobencryptsa plaintext message with Alice's public key, then Alicedecryptsthe ciphertext message with her private key. Since Alice is the only one with access to the private key, the encrypted message cannot be read by anyone besides Alice. ...
The concept of hard-driveencryptionis simple: when a file is written to the drive, it is automatically encrypted by specializedsoftware. Though it sounds similar to hardware-based encryption, it does not rely on the use of any hardware to encrypt the hard drive. When a file is read from t...
Steganography and cryptography share the same goal – which is to protect a message or information from third parties – but they use different mechanisms to achieve it. Cryptography changes the information to ciphertext which can only be understood with a decryption key. This means that if someon...
GPG takes the private key, asks you for a password, and uses the password to encrypt the private key. Then it outputs the ciphertext private key. It is doing automatically exactly what I think you imagined doing manually when you asked about whether to "further encrypt it w...
The SCP Command Syntax Before going into the explanation of how the SCP command works, let’s take a look at its basic syntax: scp [-12346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file] [-l limit] [-o ssh_option] [-P port] [-S program] ...
MASTER_SSL_CIPHER: Use SOURCE_SSL_CIPHER. MASTER_SSL_CRL: Use SOURCE_SSL_CRL. MASTER_SSL_CRLPATH: Use SOURCE_SSL_CRLPATH. MASTER_SSL_KEY: Use SOURCE_SSL_KEY. MASTER_SSL_VERIFY_SERVER_CERT: Use SOURCE_SSL_VERIFY_SERVER_CERT. MASTER_TLS_VERSION: Use SOURCE_TLS_VERSION. MASTER_...

Applications that use DTLS over UDP can use the SSPI model in Windows Server 2012 and Windows 8. Certain cipher suites are available for configuration, similar to how you can configure TLS. Schannel continues to use the CNG cryptographic provider which takes advantage of FIPS 140 certif...
