Hi everybody, I'm using OpenSSL 0.9.8i in an embedded project and I have a question related to the (relatively new?) functions to perform AES key wrapping resp. unwrapping. Are these functions meant to be used for in-place operation, i.e. the source and destination buffers are the same? Looking at the sources in aes_wrap.c, I'd say they are not at the moment, because of a memcpy() right at the beginning:
memcpy(out + 8, in, inlen); resp. memcpy(out, in + 8, inlen); If in and out point tho the same location, this will result in a memcpy of overlapping memory regions, which leads to undefined behaviour. Would it be sufficient to replace these memcpy() calls with memmove()? I didn't find any documentation about these function in the doc/ subdirectory.
