Subject: [PATCH 14/25] crypto: crypto4xx - fix off-by-one AES-OFB
|
|
|
|
I used aes-cbc as a template for ofb. But sadly I forgot
|
|
to update set_key method to crypto4xx_setkey_aes_ofb().
|
|
|
|
this was caught by the testmgr:
|
|
alg: skcipher: Test 1 failed (invalid result) on encr. for ofb-aes-ppc4xx

|
|
With the correct set_key method, the aes-ofb cipher passes the test.
