The issue is that a blkcipher is a synchronous version of the skcipher. So, you could easily move from blkcipher to skcipher and just rename the invoked API, provided you change the initialization to the following which triggers a synchronous operation: tfm = crypto_alloc_skcipher(kccavs_test->name, 0, CRYPTO_ALG_ASYNC); Note, you can only use ciphers marked as blkcipher or cipher in /proc/crypto with that. If you want to use all symmetric cipher implementation, you must use the async skcipher operation which is identical to the previous ablkcipher API. An example is given in the crypto API documentation, such as http:// www.chronox.de/crypto-API/Code.html#id-1.8.2 Ciao Stephan -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
