function New-VenafiSession { <# .SYNOPSIS Create a new Venafi TPP or Venafi as a Service session .DESCRIPTION Authenticate a user and create a new session with which future calls can be made. Key based username/password and windows integrated are supported as well as token-based integrated, oauth, and certificate. By default, a session variable will be created and automatically used with other functions unless -PassThru is used. Tokens and VaaS keys can be saved in a vault for future calls. .PARAMETER Server Server or url to access vedsdk, venafi.company.com or https://venafi.company.com. If AuthServer is not provided, this will be used to access vedauth as well for token-based authentication. If just the server name is provided, https:// will be appended. .PARAMETER Credential Username and password used for key and token-based authentication. Not required for integrated authentication. .PARAMETER ClientId Applcation Id configured in Venafi for token-based authentication .PARAMETER Scope Hashtable with Scopes and privilege restrictions. The key is the scope and the value is one or more privilege restrictions separated by commas, @{'certificate'='delete,manage'}. Scopes include Agent, Certificate, Code Signing, Configuration, Restricted, Security, SSH, and statistics. For no privilege restriction or read access, use a value of $null. For a scope to privilege mapping, see https://docs.venafi.com/Docs/current/TopNav/Content/SDK/AuthSDK/r-SDKa-OAuthScopePrivilegeMapping.php Using a scope of {'all'='core'} will set all scopes except for admin. Using a scope of {'all'='admin'} will set all scopes including admin. Usage of the 'all' scope is not suggested for production. .PARAMETER State A session state, redirect URL, or random string to prevent Cross-Site Request Forgery (CSRF) attacks .PARAMETER AccessToken PSCredential object with the access token as the password. .PARAMETER VaultAccessTokenName Name of the SecretManagement vault entry for the access token; the name of the vault must be VenafiPS. This value can be provided standalone or with credentials. First time use requires it to be provided with credentials to retrieve the access token to populate the vault. With subsequent uses, it can be provided standalone and the access token will be retrieved without the need for credentials. .PARAMETER RefreshToken PSCredential object with the refresh token as the password. An access token will be retrieved and a new session created. .PARAMETER VaultRefreshTokenName Name of the SecretManagement vault entry for the refresh token; the name of the vault must be VenafiPS. This value can be provided standalone or with credentials. Each time this is used, a new access and refresh token will be obtained. First time use requires it to be provided with credentials to retrieve the refresh token and populate the vault. With subsequent uses, it can be provided standalone and the refresh token will be retrieved without the need for credentials. .PARAMETER Jwt JSON web token. Available in TPP v22.4 and later. Ensure jwt mapping has been configured in VCC, Access Management->JWT Mappings. .PARAMETER Certificate Certificate for token-based authentication .PARAMETER AuthServer If you host your authentication service, vedauth, is on a separate server than vedsdk, use this parameter to specify the url eg., venafi.company.com or https://venafi.company.com. If AuthServer is not provided, the value provided for Server will be used. If just the server name is provided, https:// will be appended. .PARAMETER VaasKey Api key from your Venafi as a Service instance. The api key can be found under your user profile->preferences. Provide a credential object with the api key as the password. https://docs.venafi.cloud/DevOpsACCELERATE/API/t-cloud-api-key/ .PARAMETER VaultVaasKeyName Name of the SecretManagement vault entry for the Venafi as a Service key. First time use requires it to be provided with -VaasKey to populate the vault. With subsequent uses, it can be provided standalone and the key will be retrieved with the need for -VaasKey. .PARAMETER SkipCertificateCheck Bypass certificate validation when connecting to the server. This can be helpful for pre-prod environments where ssl isn't setup on the website or you are connecting via IP. .PARAMETER PassThru Optionally, send the session object to the pipeline instead of script scope. .OUTPUTS VenafiSession, if -PassThru is provided .EXAMPLE New-VenafiSession -Server venafitpp.mycompany.com Create key-based session using Windows Integrated authentication .EXAMPLE New-VenafiSession -Server venafitpp.mycompany.com -Credential $cred Create key-based session using Windows Integrated authentication .EXAMPLE New-VenafiSession -Server venafitpp.mycompany.com -ClientId MyApp -Scope @{'certificate'='manage'} Create token-based session using Windows Integrated authentication with a certain scope and privilege restriction .EXAMPLE New-VenafiSession -Server venafitpp.mycompany.com -Credential $cred -ClientId MyApp -Scope @{'certificate'='manage'} Create token-based session .EXAMPLE New-VenafiSession -Server venafitpp.mycompany.com -Certificate $myCert -ClientId MyApp -Scope @{'certificate'='manage'} Create token-based session using a client certificate .EXAMPLE New-VenafiSession -Server venafitpp.mycompany.com -AuthServer tppauth.mycompany.com -ClientId MyApp -Credential $cred Create token-based session using oauth authentication where the vedauth and vedsdk are hosted on different servers .EXAMPLE $sess = New-VenafiSession -Server venafitpp.mycompany.com -Credential $cred -PassThru Create session and return the session object instead of setting to script scope variable .EXAMPLE New-VenafiSession -Server venafitpp.mycompany.com -AccessToken $accessCred Create session using an access token obtained outside this module .EXAMPLE New-VenafiSession -Server venafitpp.mycompany.com -RefreshToken $refreshCred -ClientId MyApp Create session using a refresh token .EXAMPLE New-VenafiSession -Server venafitpp.mycompany.com -RefreshToken $refreshCred -ClientId MyApp -VaultRefreshTokenName TppRefresh Create session using a refresh token and store the newly created refresh token in the vault .EXAMPLE New-VenafiSession -VaasKey $cred Create session against Venafi as a Service .EXAMPLE New-VenafiSession -VaultVaasKeyName vaas-key Create session against Venafi as a Service with a key stored in a vault .LINK http://VenafiPS.readthedocs.io/en/latest/functions/New-VenafiSession/ .LINK
