Base64

Base 64 very useful, but limited on PowerShell cause of max string length 8191chars.

By checking md5sum we can check if successfull

• First we check md5sum

• md5sum id_rsa

• Base 64 encode and print it to console:

• cat id_rsa |base64 -w 0;echo

• On the Windows PS we can now paste the output in and write those bytes:

• [IO.File]::WriteAllBytes(“C:\Users\Public\id_rsa”, [Convert]::FromBase64String(“LS0tLS1CRUdJTiBPUEVOU1NIIFBSSVZBJuTnphQzFFYm05dVpRQUFBQUFBQUFBQkFBQUFsd0FBQUQo=”))

• And now we can confirm the md5-hash on PowerShell:

• Get-FileHash C:\Users\Public\id_rsa -Algorithm md5
