It generates the header key and the secondary header key (XTS mode) using PBKDF2 with a 512-bit salt. By default they go through 200,000 to 500,000 iterations, depending on the underlying hash function used and whether it is system or non-system encryption. [14] The user can customize it to start as low as 2,048 and 16,000 respectively. [14]
The Advanced Encryption Standard (AES), also known by its original name Rijndael (Dutch pronunciation: [ˈrɛindaːl]), [5] is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001.
In computer architecture, 512-bit integers, memory addresses, or other data units are those that are 512 bits (64 octets) wide. Also, 512-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers , address buses , or data buses of that size.
The first RSA-512 factorization in 1999 used hundreds of computers and required the equivalent of 8,400 MIPS years, over an elapsed time of about seven months. [29] By 2009, Benjamin Moody could factor an 512-bit RSA key in 73 days using only public software (GGNFS) and his desktop computer (a dual-core Athlon64 with a 1,900 MHz CPU). Just less ...
The main external difference with ChaCha20 is its 64 byte (512 bit) block size, in comparison to 16 bytes (128 bit) with both AES-128 and AES-256. The larger block size enables higher performance on modern CPUs and allows for larger streams before the 32 bit counter overflows. ChaCha20-Poly1305 Encryption

Ciright platform incorporates 512 bit encryption at the device level. This means that the computer which pushed the document to the cloud initially is the only computer that has the ability to access it later. [12] All data on the Ciright platform is thereby protected, and it is also backed up in perpetuity. [13]
Both ciphers are built on a pseudorandom function based on add–rotate–XOR (ARX) operations — 32-bit addition, bitwise addition (XOR) and rotation operations. The core function maps a 256-bit key, a 64-bit nonce, and a 64-bit counter to a 512-bit block of the key stream (a Salsa version with a 128-bit key also exists). This gives Salsa20 ...
