OpenKeychain
OpenKeychain is a free and open-source mobile app for the Android operating system that provides strong, user-based encryption which is compatible with the OpenPGP standard. This allows users to encrypt, decrypt, sign, and verify signatures for text, emails, and files. The app allows the user to store the public keys of other users with whom they interact, and to encrypt files such that only a specified user can decrypt them. In the same manner, if a file is received from another user and its public keys are saved, the receiver can verify the authenticity of that file and decrypt it if necessary. As of August 2021, it is no longer actively developed. K-9 Mail Support Together with K-9 Mail, it supports end-to-end encrypted emails via the OpenPGP INLINE and PGP/MIME formats. The developers of OpenKeychain and K-9 Mail are trying to change the way user interfaces for email encryption are designed. They propose to remove the ability to create encrypted-only emails and hide the case ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Android Privacy Guard
Android Privacy Guard (APG) is a free and open-source app for the Android operating system that provides strong, user-based encryption which is compatible with the Pretty Good Privacy (PGP) and GNU Privacy Guard (GPG) programs. This allows users to encrypt, decrypt, digitally sign, and verify signatures for text, emails, and other files. The application allows the user to store the credentials of other users with whom they interact, and to encrypt files such that only a specified user can decrypt them. In the same manner, if a file is received from another user and its credentials are saved, the receiver can verify the authenticity of that file and decrypt it if necessary. The specific implementation in APG relies on the Spongy Castle APIs. APG has not been updated since March 2014 and is no longer under active development. The development has been picked up by OpenKeychain. Reception After its initial release in June 2010, it has gained a strong following with over 200 ...

Java (programming Language)
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers ''write once, run anywhere'' ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. , Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers. Java was originally developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Open Technology Fund
The Open Technology Fund (OTF) is an American nonprofit corporation that aims to support global Internet freedom technologies. Its mission is to "support open technologies and communities that increase free expression, circumvent censorship, and obstruct repressive surveillance as a way to promote human rights and open societies." As of November 2019, the Open Technology Fund became an independent nonprofit corporation and a grantee of the U.S. Agency for Global Media. Until its formation as an independent entity, it had operated as a program of Radio Free Asia. History The Open Technology Fund was created in 2012 as a pilot program within Radio Free Asia. Under U.S. Secretary of State Hillary Clinton, the State Department adopted a policy of supporting global internet freedom initiatives. At this time, RFA began looking into technologies that helped their audiences avoid censorship and surveillance. Journalist Eli Lake argued that Clinton's policy was "heavily influenced by the ...

Public Key Fingerprint
In public-key cryptography, a public key fingerprint is a short sequence of bytes used to identify a longer public key. Fingerprints are created by applying a cryptographic hash function to a public key. Since fingerprints are shorter than the keys they refer to, they can be used to simplify certain key management tasks. In Microsoft software, "thumbprint" is used instead of "fingerprint." Creating public key fingerprints A public key fingerprint is typically created through the following steps: # A public key (and optionally some additional data) is encoded into a sequence of bytes. To ensure that the same fingerprint can be recreated later, the encoding must be deterministic, and any additional data must be exchanged and stored alongside the public key. The additional data is typically information which anyone using the public key should be aware of. Examples of additional data include: which protocol versions the key should be used with (in the case of PGP fingerprints); ...

Trusted Execution Environment
A trusted execution environment (TEE) is a secure area of a main processor. It guarantees code and data loaded inside to be protected with respect to confidentiality and integrity. Data integrity prevents unauthorized entities from outside the TEE from altering data, while code integrity prevents code in the TEE from being replaced or modified by unauthorized entities, which may also be the computer owner itself as in certain DRM schemes described in SGX. This is done by implementing unique, immutable, and confidential architectural security such as Intel Software Guard Extensions (Intel SGX) which offers hardware-based memory encryption that isolates specific application code and data in memory. Intel SGX allows user-level code to allocate private regions of memory, called enclaves, which are designed to be protected from processes running at higher privilege levels. A TEE as an isolated execution environment provides security features such as isolated execution, integrity of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
