![]() # encoded_base64_length( $bytes ) # encoded_base64_length( $bytes, $eol ) This is a variant of the base64 encoding which does not use padding, does not break the string into multiple lines and use the characters "-" and "_" instead of "+" and "/" to avoid using reserved URL characters. $decoded = MIME::Base64::decode($encoded) Īdditional functions not exported by default: # encode_base64url( $bytes ) # decode_base64url( $str )Įncode and decode according to the base64 scheme for "URL applications". $encoded = MIME::Base64::encode($decoded) If you prefer not to import these routines into your namespace, you can call them as: use MIME::Base64 () Characters occurring after a '=' padding character are never decoded. This function takes a single argument which is the string to decode and returns the decoded data.Īny character not part of the 65-character base64 subset is silently ignored. # decode_base64( $str )ĭecode a base64 string by calling the decode_base64() function. Use the Encode module to select the byte encoding you want. The base64 encoding is only defined for single-byte characters. The function will croak with "Wide character in subroutine entry" if $bytes contains characters with code above 255. Pass an empty string as second argument if you do not want the encoded string to be broken into lines. The returned encoded string is broken into lines of no more than 76 characters each and it will end with $eol unless it is empty. The second argument is the line-ending sequence to use. The first argument is the byte string to encode. The following primary functions are provided: # encode_base64( $bytes ) # encode_base64( $bytes, $eol ) Įncode data by calling the encode_base64() function. A 65-character subset () of US-ASCII is used, enabling 6 bits to be represented per printable character. The base64 encoding is designed to represent arbitrary sequences of octets in a form that need not be humanly readable. This module provides functions to encode and decode strings into and from the base64 encoding specified in RFC 2045 - MIME (Multipurpose Internet Mail Extensions). ![]() $decoded = decode_base64($encoded) #DESCRIPTION $encoded = encode_base64('Aladdin:open sesame') Here we discuss the introduction and examples of PowerShell Base64 for better understanding.MIME::Base64 - Encoding and decoding of base64 strings #SYNOPSIS use MIME::Base64 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 $co | Write-Host "Demo of encoding to hex values" -ForegroundColor Green Write-Host "Error occurred" -ForegroundColor Red ::Default.GetString(::FromBase64String($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 ::Unicode.GetString(::FromBase64String(texttobedecoded')) Examples of PowerShell Base64
