I'm facing the same issue in pysqlcipher. I found a workaround, in: https://github.com/sqlcipher/sqlcipher/pull/195/commits/37efb6a9e9995c21a3c9e632bb86b3ba6f613f79#diff-c2495c7f2211a99fba2bfb98a19a1916
They key to avoid the segfault is this line in the sqlcipher_openssl_cipher function: + EVP_CipherInit_ex(ectx, NULL, NULL, key, iv, mode); - EVP_CipherInit(ectx, NULL, key, iv, mode); Note that it just uses the _ex version. I'm not familiar enough with openssl to know if this is a bad usage on the side of sqlcipher, or it's just a bug in openssl. Already sent the patch to sqlcipher, but they replied that a new release with openssl 1.1 support will be released soon.
