在查看原始 jBCrypt v0.1 C# 端口中的错误后:BCrypt.net(相关问题)。我决定将新的 jBCrypt 代码与旧的 C# 端口进行比较,以查找差异和潜在问题,例如相关问题的错误。
这是我发现的:
// original java (jBCrypt v0.3):
private static int streamtoword(byte data[], int offp[]) {
int i;
int word = 0;
int off = offp[0];
for (i = 0; i < 4; i++) {
word = (word << 8) | (data[off] & 0xff);
off = (off + 1) % data.length;
}
offp[0] = off;
return word;
}
// port to C# :
private static uint StreamToWord(byte[] data, ref int offset)
{
uint word = 0;
for (int i = 0; i < 4; i++)
{
// note the difference with the omission of "& 0xff"
word = (word << 8) | data[offset];
offset = (offset + 1) % data.Length;
}
return word;
}
如果先验不正确,下面会修复它吗?
private static uint StreamToWord(byte[] data, ref int[] offsetp)
{
uint word = 0;
int offset = offsetp[0];
for (int i = 0; i < 4; i++)
{
word = (word << 8) | (uint)(data[offset] & 0xff);
offset = (offset + 1) % data.Length;
}
offsetp[0] = offset;
return word;
}
