FileVaultFileVault is a disk encryption program in Mac OS X 10.3 Panther (2003) and later. It performs on-the-fly encryption with volumes on Mac computers. FileVault was introduced with Mac OS X 10.3 Panther, and could only be applied to a user's home directory, not the startup volume. The operating system uses an encrypted (a large single file) to present a volume for the home directory. Mac OS X 10.5 Leopard and Mac OS X 10.6 Snow Leopard use more modern which spread the data over 8 MB files (called bands) within a bundle.
Off-the-Record MessagingOff-the-Record Messaging (OTR) is a cryptographic protocol that provides encryption for instant messaging conversations. OTR uses a combination of AES symmetric-key algorithm with 128 bits key length, the Diffie–Hellman key exchange with 1536 bits group size, and the SHA-1 hash function. In addition to authentication and encryption, OTR provides forward secrecy and malleable encryption. The primary motivation behind the protocol was providing deniable authentication for the conversation participants while keeping conversations confidential, like a private conversation in real life, or off the record in journalism sourcing.
Signal (software)Signal is an encrypted messaging service for instant messaging, voice, and video calls. The instant messaging function includes sending text, voice notes, , videos, and . Communication may be one-to-one between users, or for group messaging. The application uses a centralized computing architecture, and is cross-platform software. It is developed by the non-profit Signal Foundation and its subsidiary, Signal Messenger LLC. Signal's software is free and open-source. Its mobile clients, desktop client and server are all published under the AGPL-3.

Julian AssangeJulian Paul Assange (əˈsɑːnʒ ; Hawkins; born 3 July 1971) is an Australian editor, publisher, and activist who founded WikiLeaks in 2006. He came to wide international attention in 2010 when WikiLeaks published a series of leaks from US Army intelligence analyst Chelsea Manning: footage of an airstrike in Baghdad, military logs from the Afghanistan and Iraq wars, and US diplomatic cables. Assange was raised in several towns in Australia until his family settled in Melbourne in his mid-teens.
CiphertextIn cryptography, ciphertext or cyphertext is the result of encryption performed on plaintext using an algorithm, called a cipher. Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it. This process prevents the loss of sensitive information via hacking. Decryption, the inverse of encryption, is the process of turning ciphertext into readable plaintext.
Security through obscuritySecurity through obscurity (or security by obscurity) is the reliance on secrecy as the main method of providing security to a system or component, specifically in security engineering, whether on design or implementation. An early opponent of security through obscurity was the locksmith Alfred Charles Hobbs, who in 1851 demonstrated to the public how state-of-the-art locks could be picked. In response to concerns that exposing security flaws in the design of locks could make them more vulnerable to criminals, he said: "Rogues are very keen in their profession, and know already much more than we can teach them.
