EKON 25 Slides

By Arnaud Bouchez, 2021-11-16. Open Source › mORMot Framework

EKON 25 at Düsseldorf was a great conference (konference?).

At last, a physical gathering of Delphi developers, mostly from Germany, but also from Europe - and even some from USA! No more virtual meetings, which may trigger the well known 'Abstract Error' on modern pascal coders.
There were some happy FPC users too - as I am now.

I have published the slides of my conferences, mostly about mORMot 2.
By the way, I wish we would be able to release officially mORMot 2 in December, before Christmas. I think it starts to be stabilized and already known to be used on production. We expect no more breaking change in the next weeks.

mORMot 2 on Ampere AARM64 CPU

By Arnaud Bouchez, 2021-08-17. Open Source › mORMot Framework

Last weeks, we have enhanced mORMot support to one of the more powerful AARM64 CPU available: the Ampere Altra CPU, as made available on the Oracle Cloud Infrastructure.

Long story short, this is an amazing hardware to run on server side, with performance close to what Intel/AMD offers, but with almost linear multi-core scalability. The FPC compiler is able to run good code on it, and our mORMot 2 library is able to use the hardware accelerated opcodes for AES, SHA2, and crc32/crc32c.

OpenSSL 1.1.1 Support for mORMot 2

By Arnaud Bouchez, 2021-02-22. Open Source › mORMot Framework

Why OpenSSL? OpenSSL is the reference library for cryptography and secure TLS/HTTPS communication. It is part of most Linux/BSD systems, and covers a lot of use cases and algorithms. Even if it had some vulnerabilities in the past, it has been audited and validated for business use. Some algorithms […]

Fastest AES-PRNG, AES-CTR and AES-GCM Delphi implementation

By Arnaud Bouchez, 2021-02-13. Open Source › mORMot Framework

Last week, I committed new ASM implementations of our AES-PRNG, AES-CTR and AES-GCM for mORMot 2.
They handle eight 128-bit at once in an interleaved fashion, as permitted by the CTR chaining mode. The aes-ni opcodes (aesenc aesenclast) are used for AES process, and the GMAC of the AES-GCM mode is computed using the pclmulqdq opcode.

Resulting performance is amazing: on my simple Core i3, I reach 2.6 GB/s for aes-128-ctr, and 1.5 GB/s for aes-128-gcm for instance - the first being actually faster than OpenSSL!
