a sister project for
Qt5 developers is available as
newer and has more features with smaller footprint and can be configured to

features and highlights
- small size: the
mbedcryptois less than
250KBin size (as single shared library and stripped under Linux and OS X) with all predefined algorithms. it can be easily embedded into your service or application.
- easy to use: although cryptographynote is
complex and complicated,
mbedcryptohides most of the complexities, tries to be easy to use and hard to misuse.
- portable: needs an standard
c++14compiler and compliant
stl, compiled and tested by:
g++ 5.x+ / 6+under
msvc 2015community edition under
- low dependency:
- high+low level: both high level (c++ objects / exception) and low level (c pointer / error code) functions are available.
- highly configurable: to add or remove the algorithms, simply change
cmakebuild options. see build options
- optional support for Qt5: optional support for Qt5's
QByteArrayis also available.
following algorithms are included in
mbedcrypto in default build (see
binary/text conversions: see wiki: samples
hashes (message digest): see wiki: samples

ciphers (symmetric): see wiki: samples

cryptography is both complex and complicated, it requires a vast knowledge of mathematics, concepts, principles, algorithms, standards, conventions, continuous investigation of attacks, ...
As cryptography is mostly used to protect sensitive data, writing a library for it is a daunting task and difficult by any factor.
So instead of writing a library from scratch,
mbedcrypto stands on the
shoulders of giants,
mbedtls is this case.
Although mbedtls is mostly a
library for embedded devices, it has already implemented the most famous and
widely used cryptographic algorithms and actively developed and maintained.
mbedtls has cleaner code than
openssl, it's easier to read, use
and maintain, and it has been designed for efficiency and portability from
scratch (for embedded devices), and has many advantages over
openssl like as
readability, size, compiling and setup, … to name a few.
- implementing an easy-to-use, lightweight and portable
c++library for cryptography are the main purpose of
- there are many more algorithms in cryptographic libraries, the focus of
mbedcryptois on the most important or widely used algorithms, tries to be simple and not to bloat your application.
- as mentioned in notes, the cryptography can be divided into several areas of study and best practices, I'm not a guru nor a specialist in this field.
If you have any ideas, critiques, suggestions or whatever you want to call it, please open an issue. I'll be happy to hear from you what you'd see in this lib. I think about all suggestions, and I try to add those that make sense.
