OpenSSL version: (From opensslv.h)

Problem:
Sending an empty string to EVP_EncryptUpdate() causes this message and
core/program exception:
.\crypto\evp\evp_enc.c(282): OpenSSL internal error, assertion failed: inl 0
As an aside, this works fine on Unix
Compile string:
cl /wd4996 /EHsc -D _CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES=1
/I/openssl/include /W3 /Zi openssl_bug.c ws2_32.lib advapi32.lib ws2_32.lib
advapi32.lib user32.lib gdi32.lib /link /libpath:c:\openssl\lib libeay32.lib
ssleay32.lib
Sample code:
#include stdio.h
#include string.h
#include openssl/evp.h
int main ()
{
const EVP_CIPHER *cipher = EVP_bf_cbc ();
EVP_CIPHER_CTX ctx;
char* plaintext = test;
unsigned char encrypted_block[1024];
unsigned char *encrypted = encrypted_block;
int encrypted_size;
EVP_CIPHER_CTX_init (ctx);
EVP_EncryptInit (ctx,
cipher,
NULL,
NULL);
// Works
if (!EVP_EncryptUpdate(ctx,
encrypted,
encrypted_size,
plaintext,
strlen(plaintext))) {
printf (Failure @ #1\n);
} else {
printf (Success @ #1\n);
}
// Doesn't work (cores actually)
plaintext[0] = '\0';
if (!EVP_EncryptUpdate(ctx,
encrypted,
encrypted_size,
plaintext,
strlen(plaintext))) {
printf (Failure @ #2\n);
} else {
printf (Success @ #2\n);
}
}
Let me know if you need any additional information,
