RSA keys in DER format

[Saketaram]

In nRF SDK 1.2.0 and 1.3.0, there is a function to generate the public/private RSA keys in http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/nrf_security/doc/api.html#_CPPv422mbedtls_rsa_gen_key_fn

But is there any library available to write the generated RSA public key in DER format?
That would be similar to mbedtls_pk_write_pubkey_der in https://github.com/ARMmbed/mbedtls/blob/development/library/pkwrite.c

We expect the public key to be imported with https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/importKey#SubjectPublicKeyInfo

Let us know,

Thanks, and stay safe!

Hi Saketaram, 

The support staff is reduced during the summer holidays, and you may experience delayed answers.
