RSA key pair generator
To use RSA with Mbed TLS or any other application, you will most likely need an RSA key pair. An RSA key pair is often stored in either a PEM file or a DER file. Building the RSA key pair generatorMbed TLS ships with the source code for an RSA key pair generator application, called gen_key. To build the executable for the application, please check out the building Mbed TLS. After the compilation, the executable is often located in programs/pkey/gen_key. The gen_key application has the following arguments and options: usage: gen_key param=... acceptable parameters: type=rsa|ec default: rsa rsa_keysize=%d default: 4096 ec_curve=%s see below filename=%s default: keyfile.key format=pem|der default: pem use_dev_random=0|1 default: 0 available ec_curve values: secp521r1 (default) brainpoolP512r1 secp384r1 brainpoolP384r1 secp256r1 secp256k1 brainpoolP256r1 secp224r1 secp224k1 secp192r1 secp192k1 Generating an RSA key pairTo actually generate an RSA key pair, you have to decide which size your RSA key should be. Depending on your need for security, we advise you to use at least 2048 bits, and use 4096 bits or higher if you have very high security requirements. To use the RSA key pair generator to generate a 4096 bits RSA key and save that key in PEM format in private.key, use: ./gen_key type=rsa rsa_keysize=4096 filename=private.key format=pemThe larger the requested keysize, the longer it will take to generate the key itself. You also need to take into account the performance of the system. The key generator also outputs the key in human readable format in addition to writing the key to the requested keyfile in the requested format. The output for a 1024-bit RSA key looks something like this: . Seeding the random number generator... . Generating the private key ... ok .
