Since its inception, Firefox for Linux supported the 32-bit memory architecture of the IA-32 instruction set. 64-bit builds were introduced in the 4.0 release. The 46.0 release replaced GTK 2.18 with 3.4 as a system requirement on Linux and other systems running X.Org. [179] Starting with 53.0, the 32-bit builds require the SSE2 instruction set.
Public key certificate. In cryptography, a public key certificate, also known as a digital certificate or identity certificate, is used to prove the validity. [1] [2] The certificate includes the public key and information about it, information about the identity of its owner and the digital signature of an entity that has verified the ...
Transport Layer Security ( TLS) is a cryptographic protocol designed to provide communications security over a computer network. The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible. The TLS protocol aims primarily to provide security ...
Credit card security. When you make a purchase on AOL, we'll only finish the transaction if your browser supports SSL. As you enter your credit card number, SSL encodes it so it's transmitted in a format that prevents eavesdropping or data theft. When it's received by our secure server, your credit card number is never transmitted over the ...
A brute-force attack is a cryptanalytic attack that can, in theory, be used to attempt to decrypt any encrypted data (except for data encrypted in an information-theoretically secure manner). [1] Such an attack might be used when it is not possible to take advantage of other weaknesses in an encryption system (if any exist) that would make the ...
AES is a variant of Rijndael, with a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits. By contrast, Rijndael per se is specified with block and key sizes that may be any multiple of 32 bits, with a minimum of 128 and a maximum of 256 bits. Most AES calculations are done in a particular finite field .
Even digital certificates, such as SSL, may not protect against these attacks as phishers can purchase valid certificates and alter content to mimic genuine websites or host phishing sites without SSL. Phantom domains. When publishing hyperlinks on websites, a programmer or contributor may accidentally mistype the intended URL.
Post-quantum cryptography. Post-quantum cryptography ( PQC ), sometimes referred to as quantum-proof, quantum-safe, or quantum-resistant, is the development of cryptographic algorithms (usually public-key algorithms) that are thought to be secure against a cryptanalytic attack by a quantum computer. The problem with popular algorithms currently ...
