Question

这有效

var scrypt = scrypt_module_factory();
var pwh=scrypt.crypto_scrypt(scrypt.encode_utf8("pleaseletmein"),
            scrypt.encode_utf8("SodiumChloride"),
            Math.pow(2,14), 8, 1, 224);

这失败

var scrypt = scrypt_module_factory();
var pwh=scrypt.crypto_scrypt(scrypt.encode_utf8("pleaseletmein"),
            scrypt.encode_utf8("SodiumChloride"),
            Math.pow(2,15), 8, 1, 224);

差异在于N参数是2 ^ 15而不是2 ^ 14

有什么想法吗？

Answer 1

 var scrypt = scrypt_module_factory(67108864);

解决了这个问题。感谢上面的Anton Samsonov。这是一个记忆问题。没有参数的初始化默认为32mb。如上所述初始化将内存使用量设置为64mb。

scrypt.js失败，N大于2 ^ 14
