Subject: Remove unnecessary caps in key/iv initialization loops
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=707da1e0f378f2149510037fdee162cfdb0a1a7e;p=thirdparty%2Fopenssl.git

Remove unnecessary caps in key/iv initialization loops

Drop the `&& i < 16` and `&& i < 8` guards that were carried over from
the original fixed-size arrays. The loops now fill the entire
heap-allocated buffer, with values wrapping naturally via unsigned char.
