.Synopsis Allows the secure transfer and reconciliation of a large number of files PTRfile: Protect, Transfer, Reconcile files .Description Packages source folder contents into a 7ZIP file, adding a reconciliation file to the 7ZIP file and then encrypting the contents. Send * this script * the 7ZIP package file * plus optional SecretFilename ( if using RecipientKeyName ) to the target or recipient. The source folder is not altered and only read rights are required. A log file is written at exceution to record activity. The SecretFileName can be sent via email, while the 7ZIP can go different routes due to possible size such as: * Cloud storage provider * HTTPS web file upload * SFTP transfer * USB stick At the target, unpack the contents to a folder and reconcile the results. You will need write access on the target storage. A log file is written at exceution to record activity. Your bulk file transfer is encrypted in transit. Note that if you use the SecretKey method the ecnrypted contents will only be as secure as the strength of your secret. You can use storage providers such as Dropbox, AWS S3, Google Drive, OneDrive or BackBlaze and your documents have additonal protection. A log file is produced on execution. Repeated executions on the same day will add text content to the same log file. The default log name takes the form: "ptr_files_yyyy-MM-dd.log" You will need to have installed the 7Zip4Powershell PowerShell cmdlet before using the pack or unpack actions. You can install the cmdlet by executing .\ptrFiles.ps1 -Action install -Path ".\" Author: Tom Peltonen .Parameter Action Action to perform, which can be: - Install : Install 7Zip4PowerShell - Pack : Archive the contents of a folder(s) - Unpack : Unpack the archive, but no reconfile is performed - Reconcile : Reconcile the contents in the restored folder - ReconcileFile : Generate reconfile file. The pack process does this. - ArchiveInformation : Fetch archive information .Parameter Path The path to the files and folders to pack or the path to the unpack location. The path can include a trailing * as a wildcard to only include a subset of directories. When using the trailing * for names, the filtering is only applied to immediate folder names under the parent folder. The filter does not cascade to lower folders. The path can be a local drive, mapped network drive or a network shared folder location such as \\stora\MyLibrary. The Path can also be a file containing a list of paths, one per line. To use a list file, prefix the Path value with a "@" and name the file. Do not use a folder for @ defined path. A file (@ prefix) containing a list of paths cannot contain generic path names, that is paths with trailing wildcard of "*" .Parameter RecipientKeyName The recipient of the package which is used to find the appropriate certificate for encrypting with the public key. Either the RecipientKeyName or the SecretKey is required for packing or unpacking the 7ZIP file. Using the RecipientKeyName is the most secure transfer option as a asymmetric cryptographic key is used that can only be decrypted by the holder of the private key. If you are using the RecipientKeyName, then the 7ZIP file contents can only be unzipped by the holder of the private key and the SecretFileName file. If you don't have the private, which you should not unless you are sending to yourself, then you cannot unpack the 7ZIP file. .Parameter SecretKey A tradiitional secret to encrypt or decrypt the 7ZIP package. Either the RecipientKeyName or the SecretKey is required for packing or unpacking the 7ZIP file. This method uses a symmetric cryptographic key exchange which is less secure then the RecipientKeyName approach. Note: Currently the script doe snot user Secure Strings .Parameter ArchiveFileName The location and name of the 7ZIP file. If not supplied a default 7ZIP file name will be generated in the current directory for the pack action. The default name will take the form ".\transfer_protect_yyyyMMdd_hhmm.7z" For unpack actions, the archive file name parameter is mandatory. .Parameter RootFolderName The root folder, which should be used if using wildcard (*) for the path. A guess will be made as to value if not supplied, which will work in many circumstances. .Parameter FileFilter A filter on file names. This does not filter directories. An example to only include JPEG file is "*.jpg". You can also filter on picture file names starting with "IMG*.jpg" .Parameter ReconcileFileName The name of the reconfile file name to generate during pack or use during unpack. This is a file name without path. If no value is supplied, then a default name is generated. The reconcile file is included into the root of the 7ZIP file. Once a reconcile is executed, you can delete this file from the restored location. The default name is "##protect_transfer_reconcile_files##.csv" .Parameter SecretFileName The secret file name is used with RecipientKeyName to secure the internally generated password for the 7ZIP file. When unpacking the 7ZIP file you will need access to this file if RecipientKeyName was used. If not supplied a default name is used. This file is encrypted with RecipientKeyName. The default name is the archive file name with postfix ".key" .Parameter CloudProfile The profile name to use for Install and Transfer actions. The default for Install is "UserScope". The default for "Transfer" is "default" Profile name can also be specifed with Environment variable "PTRFILES_PROFILE" .Parameter ExcludeHash Exclude the file hash from the reconcile file. As producing a file hash takes compute cycles during pack, you can select to bypass this generation to speed up the packaging. Excluding the hash does reduce the functionality of the reconciliation at unpack. .Parameter LogPath The log folder where log files are written. If the folder does not exist then it is created. You need write access rights to this location. .Notes This script has been written to use the 7ZIP function as it is open source and provides a secure encryption mechanism, plus portability on Windows, Linux and MacOS. It is also beneficial that 7ZIP has efficient compression algorithms. Compressing and packing a large data set can take significant time and also require storage space. The script does not check if you have sufficient free storage to package the source contents into a single 7ZIP file. It is your responsibility to ensure sufficient storage space exists. If you need to copy files from one directory to another accessible directory from your Windows desktop, you might consider using ROBOCOPY. If the target directory is not accessible and you want to reconcile, then this tool is appropriate. The following environment variables are supported: - PTRFILES_RECIPIENTKEYNAME - PTRFILES_PROFILE .Example # Pack and encrypt all files in folder ".\transferpack\" using a private-public key # A file with the postifx ".key" is also generated alongside the 7ZIP file .\ptrFiles.ps1 -Action pack -Path ".\transferpack\" -RecipientKeyName data@mycompany .Example # Unpack all files in 7ZIP file "transfer_protect_yyyMMdd_hhmm.7z" to folder ".\targetdir" using a private-public key # You will need the file "transfer_protect_yyyMMdd_hhmm.7z.key" to unpack the encrypted 7ZIP file .\ptrFiles.ps1 -Action unpack -ArchiveFileName "transfer_protect_yyyMMdd_hhmm.7z" -Path ".\targetdir" -RecipientKeyName data@mycompany .Example # Reconcile files in folder ".\targetdir" .\ptrFiles.ps1 -Action reconcile -Path ".\targetdir" .Example # Pack and encrypt all files in folder ".\transferpack\" using a password .\ptrFiles.ps1 -Action pack -Path ".\transferpack\" -SecretKey "fjks932c-x=23ds" .Example # Unpack all files in 7ZIP file "transfer_protect_yyyMMdd_hhmm.7z" to folder ".\targetdir" using a password .\ptrFiles.ps1 -Action unpack -ArchiveFileName "transfer_protect_yyyMMdd_hhmm.7z" -Path ".\targetdir" -SecretKey "fjks932c-x=23ds" .Example # Pack and encrypt all files in folder ".\transferpack\02*" where the folder name starts with "02" using a password .\ptrFiles.ps1 -Action
