Subject: md5: correct size arg to memset().
X-Git-Tag: v0.1.18.1~2
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=0def9f18f5ebadaede7c388db2ebf51d38cd6296;p=secnet.git

md5: correct size arg to memset().

On realistic targets the effect of the error was that the MD5 context
wasn't fully cleared.
