(PowerShell) Generate a Unique Key for an EmailDemonstrates how to generate a unique key for an email.
Add-Type -Path "C:\chilkat\ChilkatDotNet47-9.5.0-x64\ChilkatDotNet47.dll" $email = New-Object Chilkat.Email $success = $email.LoadEml("qa_data/eml/someEmail.eml") if ($success -ne $true) { $($email.LastErrorText) exit } # The ComputeGlobalKey method computes a global unique key for an email that may be used as a # key for a relational database table (or anything else). # The key is created by a digest-MD5 hash of the concatenation of the following header fields: # Message-ID, Subject, From, Date, To. (The header fields are Q/B decoded if necessary, # converted to the utf-8 encoding, concatenated, and hashed using MD5.) # The 16-byte MD5 hash is returned as an encoded string (such as base64, url, hex, etc.) # If the bFold argument is true, then the 16-byte MD5 hash is folded to 8 bytes with an XOR to produce a shorter key. $bFold = $false $key = $email.ComputeGlobalKey("hex",$bFold) $("key: " + $key) |
