OpenSSL rsa_private_decrypt錯誤：0406506c：lib（4）：func（101）：reason（108）

Question

我試圖用openssl中的函數RSA_private_decrypt的私鑰解密。演示測試程序已完成，但不幸的是它不起作用。所有代碼都在openssl中從原始測試模塊進行了修改。

我檢查了密鑰和密文，一切正常。編譯後，試圖運行該程序時出錯： 錯誤：0406506C：lib（4）：func（101）：reason（108） 這是什麼意思？如何找到原因？任何人都可以幫助我？ 謝謝大家！

錯...... 最後我找到了原因。 加密文本需要先轉換爲HEX。 我這樣做後，它運作良好。 這真是一個愚蠢的問題。
