Hello,
I have read the crypto library documentation on chronox.de.
I used there sample code for symmetric key cipher operation.
However in the check:
skcipher = crypto_alloc_skcipher("cbc-aes-aesni", 0, 0);
if (IS_ERR(skcipher)) {
pr_info("could not allocate skcipher handle\n");
return PTR_ERR(skcipher);
}
I get could not allocate skcipher handle.
I have loaded all possible related modules for crypto:
lsmod (relevant):
algif_skcipher 32768 0
algif_hash 20480 0
algif_aead 20480 0
af_alg 24576 3 algif_aead,algif_hash,algif_skcipher
cryptd
ablk_helper.
What am I missing here?
Also IS_ERR checks if the skcipher value may be <1000, it may include
the NULL check right?.
Thanks.
