RSA private key signature is based on a hash algorithm, such as MD5 or SHA1. I have always thought that the signature process is: first hash of the plaintext, and then use the private key to encrypt the hash value directly. It is not so simple recently that it needs to be BER-encoded and then encrypted after the hash data.Let's look at an example first.Public Key Module : E6-C1-DB ED, 5B, AD B3 D2 A7 A9 8F E8 D8, B2, E5 E4 7A 7B EE, E3 C0, D2 F9 A D C3 CC 5F 1D AC B2 AB be 9C 9E B2 A7 2E E6 FA C

For example, the built-in variable $uri provided by the Ngx_http_core module can be used to obtain the URI of the current request (decoded and without request parameters), while $request _uri is used to obtain the most original URI of the request (without decoding and containing the request parameters). Take a look at the following example:

used to generate "G is recursive twice" when G is used. In fact, this is a function that equals natural number 2 in the qu dynasty.
2 = λ FX. [F (FX )〕,
In this case, (2g) y = g (Gy ). It defines similarly:
3 = λ FX. [F (f (FX)], 4
= Lambda FX (f (FX), and so on,
And
1 = λ FX. [FX], 0 = λ FX, [x 〕.
The "2" is more like "Two Times", and its "3" is "three times. In this way, 3 is used in a function f, that is, 3f is the operation of "recursion of F three times. Therefore, the role of 3f on Y is (
