.Synopsis GET PRIVATE SSH KEY VALUE CREATED BY: Vadim Melamed, EMAIL: vmelamed5@gmail.com .DESCRIPTION USE THIS FUNCTION TO GET PRIVATE SSH KEY VALUE OF AN ACCOUNT IN CYBERARK .PARAMETER token HashTable of data containing various pieces of login information (PVWA, LoginToken, HeaderType, etc). If -token is not passed, function will use last known hashtable generated by New-VPASToken .PARAMETER safe Safe name that will be used to query for the target account if no AcctID is passed .PARAMETER username Username that will be used to query for the target account if no AcctID is passed .PARAMETER platform PlatformID that will be used to query for the target account if no AcctID is passed .PARAMETER address Address that will be used to query for the target account if no AcctID is passed .PARAMETER AcctID Unique ID that maps to a single account, passing this variable will skip any query functions .PARAMETER Reason Define a reason for connecting for audit purposes .PARAMETER SaveToFile The key will be saved to a PEM file .PARAMETER HideOutput Suppress any output to the console .EXAMPLE $SSHKey = Get-VPASAccountPrivateSSHKey -reason {REASON VALUE} -safe {SAFE VALUE} -address {ADDRESS VALUE} .OUTPUTS SSH key of target account if successful $false if failed #> function Get-VPASAccountPrivateSSHKey{ [OutputType([String],[bool])] [CmdletBinding()] Param( [Parameter(Mandatory=$false,ValueFromPipelineByPropertyName=$true,Position=0)] [String]$safe, [Parameter(Mandatory=$false,ValueFromPipelineByPropertyName=$true,Position=1)] [String]$platform, [Parameter(Mandatory=$false,ValueFromPipelineByPropertyName=$true,Position=2)] [String]$username, [Parameter(Mandatory=$false,ValueFromPipelineByPropertyName=$true,Position=3)] [String]$address, [Parameter(Mandatory=$true,ValueFromPipelineByPropertyName=$true,HelpMessage="Enter reason for pulling credentials (for example: 'CSTASK1234 - patching')",Position=4)] [String]$reason, [Parameter(Mandatory=$false,ValueFromPipelineByPropertyName=$true,Position=5)] [String]$AcctID, [Parameter(Mandatory=$false,ValueFromPipelineByPropertyName=$true,Position=6)] [Switch]$SaveToFile, [Parameter(Mandatory=$false,ValueFromPipelineByPropertyName=$true,Position=7)] [Switch]$HideOutput, [Parameter(Mandatory=$false,ValueFromPipelineByPropertyName=$true,Position=8)] [hashtable]$token ) Begin{ $tokenval,$sessionval,$PVWA,$Header,$ISPSS,$IdentityURL,$EnableTextRecorder,$AuditTimeStamp,$NoSSL,$VaultVersion,$HideWarnings,$AuthenticatedAs,$SubDomain = Get-VPASSession -token $token $CommandName = $MyInvocation.MyCommand.Name $log = Write-VPASTextRecorder -inputval $CommandName -token $token -LogType COMMAND } Process{ write-verbose "SUCCESSFULLY PARSED PVWA VALUE" write-verbose "SUCCESSFULLY PARSED TOKEN VALUE" write-verbose "SUCCESSFULLY PARSED REASON VALUE" if([String]::IsNullOrEmpty($AcctID)){ Write-Verbose "NO ACCOUNT ID PROVIDED, INVOKING HELPER FUNCTION" $AcctID = Get-VPASAccountIDHelper -token $token -safe $safe -platform $platform -username $username -address $address write-verbose "ACCOUNT ID WAS RETURNED" if($AcctID -eq -1){ $log = Write-VPASTextRecorder -inputval "COULD NOT FIND UNIQUE ACCOUNT ENTRY, INCLUDE MORE SEARCH PARAMETERS" -token $token -LogType MISC $log = Write-VPASTextRecorder -inputval "REST API COMMAND RETURNED: FALSE" -token $token -LogType MISC Write-Verbose "COULD NOT FIND UNIQUE ACCOUNT ENTRY WITH SPECIFIED PARAMETERS" Write-VPASOutput -str "COULD NOT FIND UNIQUE ACCOUNT ENTRY, INCLUDE MORE SEARCH PARAMETERS" -type E return $false } elseif($AcctID -eq -2){ $log = Write-VPASTextRecorder -inputval "COULD NOT FIND ACCOUNT WITH SPECIFIED PARAMETERS" -token $token -LogType MISC $log = Write-VPASTextRecorder -inputval "REST API COMMAND RETURNED: FALSE" -token $token -LogType MISC Write-Verbose "COULD NOT FIND ACCOUNT WITH SPECIFIED PARAMETERS" Write-VPASOutput -str "NO ACCOUNTS FOUND" -type E return $false } else{ try{ Write-Verbose "MAKING API CALL TO CYBERARK" $params = @{ reason=$reason;
