Compile fails with OpenSSL 1.1

[teskje]

Trying to make this project on Ubuntu 18.04 with OpenSSL 1.1 yields the following compiler errors:

...
cc -O2 -Wall -s -o vfdecrypt vfdecrypt.c -lcrypto
vfdecrypt.c: In function ‘apple_des3_ede_unwrap_key’:
vfdecrypt.c:215:18: error: storage size of ‘ctx’ isn’t known
   EVP_CIPHER_CTX ctx;
                  ^~~
...
vfdecrypt.c: In function ‘unwrap_v2_header’:
vfdecrypt.c:282:18: error: storage size of ‘ctx’ isn’t known
   EVP_CIPHER_CTX ctx;
                  ^~~
...
vfdecrypt.c: At top level:
vfdecrypt.c:186:10: error: storage size of ‘hmacsha1_ctx’ isn’t known
 HMAC_CTX hmacsha1_ctx;
          ^~~~~~~~~~~~
...
Makefile:20: recipe for target 'vfdecrypt' failed
make: *** [vfdecrypt] Error 1

This is due to an API change in OpenSSL 1.1, see https://stackoverflow.com/questions/42662733/evp-md-ctx-error-storage-size-of-ctx-isn-t-known.

I have resolved this editing vfdecrypt.c and recompiling. The problem was that some istanziation structures are changed with openSSL 1.1.0. I have pulled a request for this

This is already solved in another fork - https://github.com/Lekensteyn/dmg2img.
From practical point of view I would consider the repo above as a new mainline.
