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 Write-Host "encoding a csv file using base64" -ForegroundColor Green Write-Host "Hex decimal values" -ForegroundColor Green Get-content $pa -encoding by -readcount $wd -totalcount $co | Write-Host "Demo of encoding to hex values" -ForegroundColor Green Write-Host "Error occurred" -ForegroundColor Red Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64. As every sextet of bits now takes one character, the overhead is 33. It's easy to calculate that base64 produces a larger output than the original string. This encoding scheme takes every 6 bits of the input string and assigns one of 64 letters to it. ::Default.GetString(::FromBase64String($str)) Base64 encoding uses only letters a-z, A-Z, 0-9 and plus, slash and equals sign characters. 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 $outfile123 = get-content c:\vignesh\decoded.txt Each block of three input bytes is encoded to create a block of four printable characters. ::ASCII.GetString(::FromBase64String($etext)) | Out-File -Encoding "ASCII" c:\vignesh\decoded.txt Base64 encodes the input data three bytes at a time. 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 Scripting on this page tracks web page traffic, but does not change the content in any way.::Unicode.GetString(::FromBase64String(texttobedecoded')) Examples of PowerShell Base64 Use is subject to license terms and the documentation redistribution policy.

If you know of others or any novel uses of Base64 encoding, please mention them in. Images and source maps are just a couple places Base64 encoding is used. The comma and semicolon delimited snippets are the Base64 encoded binary data of integers encoded as variable-length quantities (VLQ). Returns: an equivalent encoder that encodes without adding anyįor further API reference and developer documentation see the Java SE Documentation, which contains more detailed, developer-targeted descriptions with conceptual overviews, definitions of terms, workarounds, and working code examples. Here Base64 encoding is used for the mappings field. The returned encoder instance should be used for The encoding scheme of this encoder instance is unaffected by MIME inherits the encoding from Privacy Enhanced Mail (PEM) 3. Returns an encoder instance that encodes equivalently to this one,īut without adding any padding character at the end of the encoded Base64 is a computer code using 64 characters to encode any binary string with text (it is notably used for emails). As such, MIME enforces a limit on line length of base 64-encoded data to 76 characters.
