*
* Enable support for PKCS#1 v2.1 encoding.

* Requires: MBEDTLS_MD_C, MBEDTLS_RSA_C
* Requires: MBEDTLS_RSA_C and (MBEDTLS_MD_C or MBEDTLS_PSA_CRYPTO_C).
*
* \warning If building without MBEDTLS_MD_C, you must call psa_crypto_init()
* before doing any PKCS#1 v2.1 operation.
*
* This enables support for RSAES-OAEP and RSASSA-PSS operations.
