One interesting facet of hashing, since its output is always the same length no matter the length of the input data, is that, in theory, collisions will always be within the realm of possibility, as insignificant as that possibility may be. Curiously, this is not the case for encoding, wh...
Data privacy, also called information privacy, is a subset of security that focuses on personal information. Data privacy governs how data is collected, shared, and used. Data privacy is concerned with the proper handling of sensitive information such as financial data and intellectual property data...
Essentially, the client is assuming that it knows the server’s preferred key exchange method (which, due to the simplified list of cipher suites, it probably does). This cuts down the overall length of the handshake — one of the important differences between TLS 1.3 handshakes and TLS 1.0...
This method is also called secret-key or private-key cryptography because only a single key is used during the process. There are two main types of symmetric key cryptography: Stream Cipher - A streaming algorithm encrypts plaintext bit-by-bit, a single bit at a time. The same plaintext ...
Encryption works by scrambling data using an algorithm known as an "encoder" that transforms plaintext into ciphertext (a series of random characters). To decode the ciphertext again requires a "decoder", which takes this encrypted message back into readable text form using another algorithm with...
You can think of this as the voice equivalent of OTR. Now let us introduce a major gotcha in SRTP - there is a NULL cipher which can be negotiated for "no crypto please" much like the NULL cipher in TLS. Which to use then. On initial setup, all require y...
Before the advent of computers, ciphertext was often created by simply replacing one letter with another letter in the plaintext, a method known as a "substitution cipher." For instance, suppose that someone sends a message reading "Hello" to another person, and each letter is replaced with ...
The session key encrypts the bulk of the data transmitted in the TLS handshake and is generated and negotiated independently of the protocol version andciphersuite selected by the clients and servers. As a result, the session key is the same for all connections established between two peers that...
I vaguely remember a way to tell what type of CA it is. Standalone vs. Enterprise or whatever. I believe it was the registry key Type in My Computer\HKLM\System\CurrentControlSet\Services\CertSvc but I cannot find any info. on this. Is there a way to figure out what kind of CA ...
Cipher Suites:Acipher suiteis a combination of cryptographic algorithms used in the TLS protocol. This includes an asymmetric encryption algorithm for the handshake, a symmetric encryption algorithm for encrypting the data sent over the connection, a digital signature algorithm, and a hash function use...
