base64 decode encode powershell strings utf8 Post navigation Previous Post Windows: Cancel Bits transfers from other user Next Post Mail: Generator for mail … Notepad has some logic that determines what file encoding it uses, but the default is ANSI, and that is what it uses in this example. You have an ANSI-encoded file, or a file encoded using some other (supported) encoding, and want to convert it to UTF-8 (or another supported encoding). You picked UTF-8 above, but there are other options (e.g. Stack Overflow for Teams is a private, secure spot for you and ASCII, UTF-16, etc. I'm thinking there is a simple way from the .Net libraries, but couldn't find an example.How do I convert that into a byte array that I can use on :: ComputeHash($string)?So what I have to end up with is an encrypted SHA-1 and base 64 encoded UTF-8 password, which the code above does, but it's coming back different than when I coded this same thing in java, where I encrypted it first, then converted that result to base 64 encoding. Private self-hosted questions and answers for your enterpriseProgramming and related technical career opportunitiesYou don't want FromBase64String, you want ToBase64String. If your Java code is hashing an already Base64 encoded string, then you can certainly do that in PowerShell too (but it would be unusual). What's the easiest way to convert XML from UTF16 to a UTF8 encoded file? Stack Overflow works best with JavaScript enabled Stack Overflow. A hack to list the supported encodings is to use one that doesn't exist: Ask Question Asked 11 years, 3 months ago. Apparently the .Net Framework can't do it that way is what I meant. The Overflow Blog xml powershell utf-8 utf-16. Then I when the encoding in java I get this:
Without code or sample output I'm not sure we can help.Understood, I'll add the java code in now. Correct or am I missing something here?When I run the java code with the password string of "password" I get[91, -86, 97, -28, -55, -71, 63, 63, 6, -126, 37, 11, 108, -8, 51, 27, 126, -26, -113, -40] Active 7 years, 9 months ago. The data contains the "extra" Norwegian vowels "æ", "ø" and "å", and their position in the Norwegian alphabet in a manually crafted CSV file. 5. There are no cmdlets so you would have to resort to the .NET framework and the [system.text.encoding] class. The problem occurred when I wanted to work on the CSV file using the PowerShell cmdlet Import-Csv, which, as far as I can tell, doesn't work correctly with latin1-encoded files exported from Excel or ANSI files created with notepad - if they contain non-US characters. Here you see the Norwegian vowels are incorrectly displayed as question marks ("?") You picked UTF-8 above, but there are other options (e.g. Like using a Stream instead of a byte array? Note: This answer applies to Windows PowerShell; by contrast, in the cross-platform PowerShell Core edition (v6+), UTF-8 without BOM is the default encoding, across all cmdlets.
Listing the cmdlet Set-Content's Supported EncodingsAdditional Information and Avoiding a Temporary FileListing the cmdlet Set-Content's Supported EncodingsAdditional Information and Avoiding a Temporary File Type "Get-Help Set-Content -Full" at a PowerShell prompt to read the help text, and see the example below. @James, it doesn't matter. Maybe you could give us the output that the Java program produces...The .Net Framework library. Viewed 20k times 18. I tried repeatedly to get a byte array from a string, but the only way I was successful was to use $encoding.getBytes(encodedString), not $somevariable.getBytes(regularString)The Java MessageDigest class also hashes a byte array and returns a byte array (that will match the .NET equivalent), so I'm not sure what you are getting at. Then I just pass it to Import-Csv to verify it's displayed correctly. Getting the ASCII/ UTF-8 value of a string by rakhesh is licensed under a Creative Commons Attribution 4.0 International License.
Internally in PowerShell, a string is a sequence of 16-bit Unicode characters (often called a Unicode code point or Unicode scalar value).
You can use the Export-Csv cmdlet to convert objects to CSV strings. The code in my example produces exactly the output you want.Except in this case it appears that the api requires an encoded byte array and not just a byte array.I'm not sure what you mean by "the api", but a byte array is not aware of any encoding. It looks like you're on the right track.
The objects converted from CSV are string values of the original objects that contain property values and no methods. Also see the part about using Get-Content file.csv | ConvertFrom-Csv.
I ran into this when working with exported data from Excel which was in latin1/ISO8859-1 by default, and I couldn't find a way to specify UTF-8 in Excel. which is the encryption.
The ConvertTo-CSV cmdlet returns a series of comma-separated value (CSV) strings that represent the objects that you submit. Convert to UTF-8 and Verify It Displays Correctly. Converting xml from UTF-16 to UTF-8 using PowerShell. Either way you have to map character data<=>byte data (streams are byte data). – Gaara Dec 28 '12 at 16:06. I broke things down into discrete steps. It's implemented directly using the .NET System.String type, which is a reference type (read more about that in my A string can be arbitrarily long (computer memory and physics as we currently understand it allowing) and it is immutable, meaning it can't be changed without creating an entirely new altered version/"copy" of the string. W6ph5Mm5Pz8GgiULbPgzG37mj9g=but when I run it in PowerShell I get this because it's encoded first for UTF8:91 170 97 228 201 185 63 63 6 130 37 11 108 248 51 27 126 230 143 216Then when I run this line of code to convert it I get an error:However, if I run the new line of code to make it hex from below I get:Again, this may not even be possible to do, but I'm trying to find a work-around to see.You most likely just need to convert your hash to base64 after the last line.It looks like you're on the right track. To simulate the situation, I open notepad and manually enter some data causing issues.
