Gilles Peskine	4fc21fdeb6	Implement MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG ... Implement support for MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG. For test purposes, write an implementation that uses libc rand(). Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>	2020-11-23 17:42:54 +01:00
Gilles Peskine	30524eb7e5	psa_crypto: create random and drbg abstraction ... Create wrapper functions around calls to CTR_DRBG and around calls to entropy+DRBG. This is in preparation for allowing alternative DRBG implementations that use the Mbed TLS entropy module, or complete RNG implementations that bypass the entropy module as well. This is purely a refactoring commit. No behavior change. Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>	2020-11-23 16:27:40 +01:00
Gilles Peskine	90edc99e30	Create a header file for PSA crypto random generator abstraction ... Subsequent commits will move declarations and definitions there. Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>	2020-11-23 16:27:40 +01:00
