mbedtls_x509_crt_profile Struct Reference

X509_module

Security profile for certificate verification.

All lists are bitfields, built by ORing flags from MBEDTLS_X509_ID_FLAG() .

The fields of this structure are part of the public API and can be manipulated directly by applications. Future versions of the library may add extra fields or reorder existing fields.

You can create custom profiles by starting from a copy of an existing profile, such as mbedtls_x509_crt_profile_default or mbedtls_x509_ctr_profile_none and then tune it to your needs.

For example to allow SHA-224 in addition to the default:

mbedtls_x509_crt_profile my_profile = mbedtls_x509_crt_profile_default; my_profile.allowed_mds |= MBEDTLS_X509_ID_FLAG( MBEDTLS_MD_SHA224 ) ;

Or to allow only RSA-3072+ with SHA-256:

mbedtls_x509_crt_profile my_profile = mbedtls_x509_crt_profile_none; my_profile.allowed_mds = MBEDTLS_X509_ID_FLAG( MBEDTLS_MD_SHA256 ) ; my_profile.allowed_pks = MBEDTLS_X509_ID_FLAG( MBEDTLS_PK_RSA ) ; my_profile.rsa_min_bitlen = 3072;
