![]() ![]() Here we discuss the introduction and examples of PowerShell Base64 for better understanding. It showed various examples of encoding and decoding various file type, strings, pdf file, csv file etc. Thus, the article shows in detail about the Base64 encoding technique in PowerShell. $pdffile = Get-Content "C:\Vignesh\Vyapini Birth Certificate.pdf" Write-Host "Read the pdf" -ForegroundColor Green Write-Host "Demo of encoding a pdf file" -ForegroundColor Green Write-Host "after decoding, the url is " $dcu -ForegroundColor Green Write-Host "Decoding the above encoded url" -ForegroundColor Green Write-Host "after encoding,the url is" $res -ForegroundColor Green #The below code is used to encode the URL Write-Host "url before encoding " $testurl -ForegroundColor Green Write-Host "Demo of encoding and decoding urls using base64" Write-Host "encoded output is below" -ForegroundColor Green Moreover, it supports almost all the character. Also, you can use it to convert base64 data into an image file, hex, or binary form. It decodes the base64 data and gives results in plain text. Write-Host "encoding a csv file using base64" -ForegroundColor Green Base64 Decode, also known as Base64 Converter, is a free-to-use and simple online tool that does exactly what its name suggests. Write-Host "Hex decimal values" -ForegroundColor Green Get-content $pa -encoding by -readcount $wd -totalcount $co | Write-Host "Demo of encoding to hex values" -ForegroundColor Green Write-Host "Error occurred" -ForegroundColor Red ::Default.GetString(::FromBase64String($str)) Write-Host "Decoding image file" -ForegroundColor Green ::ToBase64String((Get-Content -Path $fp -Encoding Byte)) Write-Host "Encoding the image file" -ForegroundColor Green $DecodedFile = Convert-stob -estr $b64str -fp C:\Vignesh\helloworld.exe Write-Output -InputObject (Get-Item -Path $fp) Write-Host "After decoding of exe" -ForegroundColor Green Write-Host "After encoding" -ForegroundColor Green Write-Host "Encoding of an exe file" -ForegroundColor Green Write-Host "Demo of Encoding and decoding of an exe file" -ForegroundColor Green Write-Host "Decoded text is as follows" -ForegroundColor Green $outfile123 = get-content c:\vignesh\decoded.txt ::ASCII.GetString(::FromBase64String($etext)) | Out-File -Encoding "ASCII" c:\vignesh\decoded.txt Write-Host "Decoding the above converted text" ![]() Write-Host "ENCODED text file content is " $etext -ForegroundColor Green Write-Host "Welcome to the example of powershell base64 encoding and decoding" -ForegroundColor Green $output = ::Unicode.GetString(::FromBase64String($input)) $input = “vikivikivikivikivikivyapvyapvyapvyapvyapnandnandnandnandnandviki” ![]() Given below are the examples of PowerShell Base64: Example #1 The result will be QUJD REVG R0g= (without spaces).::Unicode.GetString(::FromBase64String(texttobedecoded')) Examples of PowerShell Base64 The following are the syntax of Base64 encoding and decoding: Encoding: Convert::ToBase64String ( ::Unicode.GetBytes ('TextToEncode')) Decoding: ::Unicode.GetString ( System. Similarly, it will add one = at the end of the output to get 4 characters. Thus, the result will be QUJD REVG Rw= (without spaces). But for the third, it will add a double = in the output in order to complete the 4 needed characters. ![]() You will not have an = sign if your string has a multiple of 3 characters, because Base64 encoding takes each three bytes (a character=1 byte) and represents them as four printable characters in the ASCII standard.īase64 deals with the first block (producing 4 characters) and the second (as they are complete). The last character ( = sign) is added only as a complement (padding) in the final process of encoding a message with a special number of characters. (the word usb is base64 encoded into dXNi) Q Does a base64 string always end with =?Ī: No. ![]()
