sha1 in Go and PHP has different result

Hope that helps Your php code is encoding a 1-byte input, but your Go code is doing the same on a utf-8 encoded string. If you print len(string(164)) you'll see that it is 2-bytes. Use this:
code :
str := []byte{164}
passSha1 := sha1.New()
passSha1.Write([]byte(str))
getSha1 := passSha1.Sum(nil)
fmt.Printf("%x\n",getSha1)

PHP SHA1 gives different result than expected

To fix this issue Get rid of all the non alpha-numeric special characters - this one is even not ASCII as far as I can tell: ¤. So it might mess things up if you run sha1 under string encoded in different encodings.

Java's MessageDigest SHA1-algorithm returns different result than SHA1-function of php

like below fixes the issue It has nothing to do with the encodings. The output would be entirely different.
For starters, your function convertStringToHex() doesn't output leading zeros, that is, 07 becomes just 7.

SHA1 the PHP mcrypt_decrypt result

will help you Problem is that your decrypt_string returns 16 bytes string, that is filled with 0 bytes at the right side. It's a problem known for about 2 years.
Remove null bytes from the right with line similar to this one:
code :
return trim(mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key, $cipher, MCRYPT_MODE_CBC, $iv), "\0");

SHA1 C# result different from Python 3

I wish this helpful for you I have this code on C#: , The issue is at here,
code :
enc = str.encode('utf-8')
>>> str.encode("utf-8")
b'utf-8'
>>> help(str.encode)
Help on method_descriptor:

encode(self, /, encoding='utf-8', errors='strict')
    Encode the string using the codec registered for encoding.

    encoding
      The encoding in which to encode the string.
    errors
      The error handling scheme to use for encoding errors.
      The default is 'strict' meaning that encoding errors raise a
      UnicodeEncodeError.  Other possible values are 'ignore', 'replace' and
      'xmlcharrefreplace' as well as any other name registered with
      codecs.register_error that can handle UnicodeEncodeErrors.
enc = str.encode("testStringHere", 'utf-8') # encode in utf8
enc = "testStringHere".encode('utf-8') # encode in utf8
>>> from hashlib import sha1
>>> enc = str.encode("testStringHere", 'utf-8')
>>> enc1 = "testStringHere".encode('utf-8')
>>> sha1(enc).hexdigest() == sha1(enc1).hexdigest()
True

Why Javascript sha1 and PHP5 sha1 generate different result for utf-8 string?

Any of those help The result you are getting from PHP is correct for the string encoded as GB18030 (61 62 63 B0 AC)
The one you're getting from CryptoJS is correct for the string encoded as UTF-8 (61 62 63 E8 89 BE).
