## Definition

      #include <nitro/crypto.h>

      typedef struct CRYPTORSASignInitParam
      {
          void    *key;
          u32     key_len;
      }
      CRYPTORSASignInitParam;

## Elements

`key` | Specifies the address of the string where the RSA private key is stored.
`key_len` | Specifies the length of the string for the RSA private key.

## Description
