[Query] RSA SHA-384 signature verification

[Anshuman Gupta <anshuman.gupta@intel.com>]

Hi ,
I wanted to verify a RSA SHA-384 signature.
I am using crypto_alloc_shash(), crypto_shash_digest() API to extract
the SHA-384 digest.
I am having public key along with the sha-384 digest extracted from raw data and signature.  
AFAIU understand from crypto documentation that i need to verify the
signature by importing public key to akcipher/skcipher API.
Here i am not sure which cipher API to prefer symmetric key cipher or asymmetric key
cipher API.

There are two types of API to import the key.
crypto_skcipher_setkey()
crypto_akcipher_set_pub_key()

Also i am not sure exactly which algo to use for RSA-SHA384 signature
verification.

Any help or inputs from crypto community will highly appreciated.

Thanks ,
Anshuman Gupta.
