scrypt.js失败，N大于2^14

Question

这适用于

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);

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？

 var scrypt = scrypt_module_factory(67108864);

修复了问题。感谢上面的Anton Samsonov。这是一个记忆问题。不带参数的初始化默认为32mb。如上所述初始化会将内存使用率设置为64mb。
