 Hi there,
 
 I have a couple of applications built upon a small library function 
that I
 have written. One of these applications works fine, all the time. The 
other
[...snip...]
 
 I am using MD5. In my debug output, I consistently obtain:
 
   2.sig_len: [128]
   3.sig_len: [271733878]
 
 128 is the expected, computed, value. Why does calling 
EVP_VerifyInit()
 magically change the value of this local, non-passed integer?!
 
 Now here's a thing:
 
   $ printf %x\n 271733878
   $ 10324576

The %x in the printf statement signifies conversion to hexadecimal 
instead of printing decimal...

The number output matches what I get when I input the 2717... into my 
hex converter and let it convert.  

Regards,
Gregory Hicks

 
 Those of you that are still awake may be reminded of Word A of RFC 
3121 (MD5
 spec).
 
 
 Perhaps I did something stupid or missed something obvious?

Unfortunately, all wrong. No exciting bugs in OpenSSL 0.9.7e.

In another shared library that we are using, nm tells me that there are some
interesting functions with names like EVP_*(). Time to go and talk with a
cow-orker.
