Subject: New xcbc_ok test vector is required after the parity bits in cbc2_key
X-Git-Tag: OpenSSL_0_9_5beta1~115
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=d716308288fe73eb3b8b3166bedd780a17086736;p=oweals%2Fopenssl.git

New xcbc_ok test vector is required after the parity bits in cbc2_key
were fixed up. The catch is that in the DESX test the cbc2_key is used
as whitening key where *all* 64 bits are significant.
