What is Cryptodev-Linux?

Cryptodev-linux is a Linux-kernel device that allows user-space access to hardware cryptographic accelerators.

What is Cryptodev?

Device /dev/crypto (aka CryptoDev) is a way for userspace processes to use cryptographic algorithms provided by kernel CryptoAPI modules. For example a process that needs to AES-encrypt some data can either: Have the AES algorithm built in, or. Use an external library like OpenSSL that will do the encryption, or.

What is kernel crypto?

The kernel crypto API provides implementations of single block ciphers and message digests. In addition, the kernel crypto API provides numerous “templates” that can be used in conjunction with the single block ciphers and message digests. Templates include all types of block chaining mode, the HMAC mechanism, etc.

Does OpenSSL use hardware acceleration?

To support available hardware extensions, OpenSSL provides so-called EVP crypto APIs (e.g., EVP_Decrypt/EVP_Encrypt) which can automatically leverage hardware acceleration like AES-NI (if available) and fall back to software implementation (if not available), via a single interface.

Does OpenVPN use AES-NI?

Nothing needs selected for OpenVPN to utilize AES-NI. The OpenSSL engine has its own code for handling AES-NI that works well without using additional modules.

Does OpenSSL use AES-NI?

The result the first line will run faster (almost double on my i7 cpu). So that conclusion is that AES-NI is used by default for openssl.

How much RAM does OpenVPN need?

At a minimum, you must start with 1GB of memory, and add approximately 1GB for each 150 connected devices.

How much RAM do you need for a VPN server?

VPN Server System Requirements 128MB of RAM – we recommend 1GB of RAM for other system services. 10GB of disk space for OpenVPN and other system packages.

How do I enable AES-NI in Linux?

From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Server Security > Processor AES-NI Support and press Enter. Enabled—Enables AES-NI support.

Can I setup my own VPN?

Head into Settings > Network & Internet > Advanced > VPN (you should see a little key icon). If you don’t see Network & Internet in the Settings menu (which may happen depending on your Android overlay), then do a search within Settings for VPN. Now create your VPN profile. Add the VPN name, type, and Server address.
