* ext/openssl/ossl_cipher.c (ossl_cipher_initialize): Avoid possible
SEGV from AES encryption/decryption. Processing data by Cipher#update without initializing key (meaningless usage of Cipher object since we don't offer a way to export a key) could cause SEGV. In OpenSSL, the EVP which has EVP_CIPH_RAND_KEY flag (such as DES3) allows uninitialized key, but other EVPs (such as AES) does not allow it. Calling EVP_CipherUpdate() without initializing key causes SEGV so we set the data filled with "\0" as the key by default. See #2768. * test/openssl/test_cipher.rb: test it. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@32723 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
