IronKey Uses AES 128-bit and 256-bit CBC-mode hardware encryption; KeePass Password Safe; LastPass [7] Linux kernel's Crypto API, now exposed to userspace; NetLib Encryptionizer supports AES 128/256 in CBC, ECB and CTR modes for file and folder encryption on the Windows platform. Pidgin (software), has a plugin that allows for AES Encryption
Many platforms that provide hardware acceleration of AES encryption expose this to programs through an extension of the instruction set architecture (ISA) of the various chipsets (e.g. AES instruction set for x86). With this sort of implementation, any program (kernel-mode or user-space) may utilize these features directly.
AES-NI (or the Intel Advanced Encryption Standard New Instructions; AES-NI) was the first major implementation. AES-NI is an extension to the x86 instruction set architecture for microprocessors from Intel and AMD proposed by Intel in March 2008. [2] A wider version of AES-NI, AVX-512 Vector AES instructions (VAES), is found in AVX-512. [3]
Implementing cryptography in hardware means that part of the processor is dedicated to the task. This can lead to a large increase in speed. [ 4 ] In particular, modern processor architectures that support pipelining can often perform other instructions concurrently with the execution of the encryption instruction.
Encrypt/Decrypt data, using the AES cipher in various block modes (ECB, CBC, CFB, OFB and CTR, respectively). rCX contains the number of 16-byte blocks to encrypt/decrypt, rBX contains a pointer to an encryption key, ES:rAX a pointer to an initialization vector for block modes that need it, and ES:rDX a pointer to a control word.
dm-crypt is a transparent block device encryption subsystem in Linux kernel versions 2.6 and later and in DragonFly BSD.It is part of the device mapper (dm) infrastructure, and uses cryptographic routines from the kernel's Crypto API.
The implementation of AES in products intended to protect national security systems and/or information must be reviewed and certified by NSA prior to their acquisition and use. [ 14 ] AES has 10 rounds for 128-bit keys, 12 rounds for 192-bit keys, and 14 rounds for 256-bit keys.
Since version 3, nettle provides the AES block cipher (a subset of Rijndael) (with assembly optimizations for x86 and sparc), the ARCFOUR (also known as RC4) stream cipher (with x86 and sparc assembly), the ARCTWO (also known as RC2) stream cipher, BLOWFISH, CAMELLIA (with x86 and x86_64 assembly optimizations), CAST-128, DES and 3DES block ciphers, the ChaCha stream cipher (with assembly for ...
