सिफर 'AES256-सीबीसी' आवश्यक है, लेकिन यह उपलब्ध

Question

मैं एक SFTP JSch का उपयोग कर ऐसा करने के लिए कोशिश कर रहा हूँ नहीं है, लेकिन मैं कुछ त्रुटि हुई:

com.jcraft.jsch.JSchException: The cipher 'aes256-cbc' is required, but it is not available.

नीचे कोड मैं प्रयोग किया जाता है। क्या मुझे कुछ याद आया है?

JSch jsch = new JSch(); 
Session session = null; 

jsch.addIdentity("C:\\privatekey.ppk", "Password"); 

session = jsch.getSession("user", "54.251.240.234", 22); 
session.setConfig("StrictHostKeyChecking", "no"); 


Channel channel = session.openChannel("sftp"); 
channel.connect(); 
ChannelSftp sftpChannel = (ChannelSftp) channel; 
sftpChannel.put("C:\\Users\\test.txt", "/home/user/test.txt"); 
sftpChannel.exit(); 
session.disconnect();

Answer 1

आप अपने JRE को जोड़ने की जरूरत है - जावा असीमित ताकत नीति, जैसे .: http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html कृपया सर्वर के JRE पथ पर local_policy और us_export_policy की जगह (\ lib \ सुरक्षा) जेसीई नीतियों का अन्य संस्करण ओरेकल वेब पृष्ठों पर पाया जा सकता है।

Answer 2

डिफ़ॉल्ट रूप से, जेसीई नीतियां - जो आपके जेडीके या जेआरई के साथ आती है- इस तरह की तकनीकों का समर्थन नहीं करती है जैसे कि (एएस -256, .. आदि)।

निश्चित रूप से आपको अपने वर्तमान जेसीई जार ($ JAVA_HOME/jre/lib/security पर मौजूद) को ऑरैकल वेबसाइट से संगत जेव संस्करण के साथ बदलना होगा।

Answer 3

यह त्रुटि तब भी दिखाई देती है जब आपकी निजी कुंजी पुटी प्रारूप में होती है और खुले एसएसएच प्रारूप में नहीं होती है।

आप टूल को पुटीटीजन के साथ एक खुली एसएसएच प्रारूप निजी कुंजी में परिवर्तित कर सकते हैं।

यह मेरे लिए समस्या हल करता है। नेटबीन्स 8.0.2 और जावा 8_25 के साथ जावा फाइलों को प्रतिस्थापित करना मेरे मामले में आवश्यक नहीं था।
