rs256_pk_to_EVP_PKEY(const rs256_pk_t *pk);

DESCRIPTION

In libfido2, RS256 public keys are abstracted by the rs256_pk_t type.

The rs256_pk_new() function returns a pointer to a newly allocated, empty rs256_pk_t type. If memory cannot be allocated, NULL is returned.

The rs256_pk_free() function releases the memory backing *pkp, where *pkp must have been previously allocated by rs256_pk_new(). On return, *pkp is set to NULL. Either pkp or *pkp may be NULL, in which case rs256_pk_free() is a NOP.

The rs256_pk_from_RSA() function fills pk with the contents of rsa. No references to rsa are kept.

The rs256_pk_from_ptr() function fills pk with the contents of ptr, where ptr points to len bytes. No references to ptr are kept.

The rs256_pk_to_EVP_PKEY() function converts pk to a newly allocated EVP_PKEY type with a reference count of 1. No internal references to the returned pointer are kept. If an error occurs, rs256_pk_to_EVP_PKEY() returns NULL.
