我正在尝试查找一组可以用作加密算法的字符串列表，以替换此函数中的SHA256。
crypto.createHmac("SHA256", secret).update(string).digest('base64'),
我明白加密货币使用openssl，而且算法是特定于运行node.js的每个系统的。
使用以下命令可以查看您的系统中所有可用算法的列表。
openssl list-cipher-algorithms
openssl list-cipher-commands
我已经将这两个命令的内容输出到此Gist。
令我困扰的是，SHA256 在这些列表中都没有出现。
我真的很想得到明确的算法列表。
这里的教训是，ciphers和hashes是不同的并且使用不同的算法。在node中使用crypto对象的.getCiphers()和.getHashes()方法来分别返回支持的ciphers和hashes的名称数组。
var crypto = require('crypto')
console.log(crypto.getCiphers())
console.log(crypto.getHashes())
以下记录了哪些加密算法：
