您似乎与其他人有相同的问题OpenSSL加密未能解密C＃

You seems to have the same issue as others OpenSSL encryption failing to decrypt C#

据我所知，文档加密库使用openssl。 openssl使用其EVP_BytesToKey函数和随机盐（不仅仅是哈希）从密码创建IV和密钥。正如戴夫指出的那样，加密库不使用盐。

As far I understood the docs, the crypto libeary uses openssl. The openssl creates IV and key from the password using its EVP_BytesToKey function and random salt (not just hash). As dave pointed out, the crypto library uses no salt.

openssl的输出为Salted_ {8字节salt} {ciphertext}，因此请检查密码（我现在无法做到）
