I just change the rsa_test.c:

len2 = sizeof(tmp);
DO(rsa_export(tmp, &len2, PK_PRIVATE, &key));
DO(rsa_import(tmp, len2, &pk));
len2 = sizeof(tmp);
DO(rsa_export(tmp, &len2, PK_PUBLIC, &key));
DO(rsa_import(tmp, len2, &sk));

encrypt use private key:
DO(rsa_encrypt_key(in, rsa_msgsize, out, &len, NULL, 0, &yarrow_prng, prng_idx, hash_idx, &pk));

decrypt use public key:
DO(rsa_decrypt_key(out, len, tmp, &len2, NULL, 0, hash_idx, &stat, &key));

then the test failed, and promot is: A private PK key is required.

does anyone help me ?
