javascript-obfuscator混淆

安装

npm install javascript-obfuscator -g

配置

重度混淆，性能低

性能下降50-100%

{  "compact": true,  "controlFlowFlattening": true,  "controlFlowFlatteningThreshold": 0.75, // 设置为0到1之间的值  "deadCodeInjection": true,  "deadCodeInjectionThreshold": 0.4, // 设置为0到1之间的值  "debugProtection": true,  "debugProtectionInterval": 1000, // 设置为一个正整数，表示毫秒数  "disableConsoleOutput": true,  "identifierNamesGenerator": "hexadecimal",  "log": false,  "numbersToExpressions": true,  "renameGlobals": false,  "rotateStringArray": true,  "selfDefending": true,  "shuffleStringArray": true,  "simplify": true,  "splitStrings": true,  "splitStringsChunkLength": 5,  "stringArray": true,  "stringArrayEncoding": ["rc4"], // 确保编码类型是有效的  "stringArrayIndexShift": true,  "stringArrayWrappersCount": 5,  "stringArrayWrappersChainedCalls": true,  "stringArrayWrappersParametersMaxCount": 5,  "stringArrayWrappersType": "function",  "stringArrayThreshold": 0.75, // 设置为0到1之间的值  "transformObjectKeys": true,  "unicodeEscapeSequence": false  
}

中度压缩，最佳性能

性能下降30-35%

{  "compact": true,  "controlFlowFlattening": true,  "controlFlowFlatteningThreshold": 0.75,  "deadCodeInjection": true,  "deadCodeInjectionThreshold": 0.4,  "debugProtection": false,  "disableConsoleOutput": true,  "identifierNamesGenerator": "hexadecimal",  "log": false,  "numbersToExpressions": true,  "renameGlobals": false,  "rotateStringArray": true,  "selfDefending": true,  "shuffleStringArray": true,  "simplify": true,  "splitStrings": true,  "splitStringsChunkLength": 10,  "stringArray": true,  "stringArrayEncoding": ["base64"],  "stringArrayIndexShift": true,  "stringArrayWrappersCount": 2,  "stringArrayWrappersChainedCalls": true,  "stringArrayWrappersParametersMaxCount": 4,  "stringArrayWrappersType": "function",  "stringArrayThreshold": 0.75,  "transformObjectKeys": true,  "unicodeEscapeSequence": false  
}

轻度压缩，高性能

性能略低于压缩之前

{  "compact": true,  "controlFlowFlattening": false,  "deadCodeInjection": false,  "debugProtection": false,  "disableConsoleOutput": true,  "identifierNamesGenerator": "hexadecimal",  "log": false,  "numbersToExpressions": false,  "renameGlobals": false,  "rotateStringArray": true,  "selfDefending": true,  "shuffleStringArray": true,  "simplify": true,  "splitStrings": false,  "stringArray": true,  "stringArrayEncoding": [], // 你可以根据需要添加支持的编码算法，如 ["base64", "rc4"]  "stringArrayIndexShift": true,  "stringArrayWrappersCount": 1,  "stringArrayWrappersChainedCalls": true,  "stringArrayWrappersParametersMaxCount": 2,  "stringArrayWrappersType": "variable",  "stringArrayThreshold": 0.75,  "unicodeEscapeSequence": false  
}

默认值，高性能

{  "compact": true,  "controlFlowFlattening": false,  "deadCodeInjection": false,  "debugProtection": false,  "disableConsoleOutput": false,  "identifierNamesGenerator": "hexadecimal",  "log": false,  "numbersToExpressions": false,  "renameGlobals": false,  "rotateStringArray": true,  "selfDefending": false,  "shuffleStringArray": true,  "simplify": true,  "splitStrings": false,  "stringArray": true,  "stringArrayEncoding": [],  "stringArrayIndexShift": true,  "stringArrayWrappersCount": 1,  "stringArrayWrappersChainedCalls": true,  "stringArrayWrappersParametersMaxCount": 2,  "stringArrayWrappersType": "variable",  "stringArrayThreshold": 0.75,  "unicodeEscapeSequence": false  
}

执行

混淆整个目录里的js

javascript-obfuscator ./js --output ./js/obfuscated --config obfuscator.json

混淆单个js

javascript-obfuscator index.af5ba3a0.js --output index.af5ba3a011111.js --config obfuscator.json
