+
+## Notes
+
+This is an initial, minimally tested release; proceed with care and report all issues.
+
+Setting up Client Side Encryption is not for the faint of heart; here is a start.
+* https://support.google.com/a/answer/10741897?hl=en&ref_topic=10742486&sjid=10342493441460488213-NA
+
+Do I personally understand what's going on here? No, I just added the API calls to GAM.
+
+Two sets of files are required for Gmail CSE, these two variables in `gam.cfg` control where GAM looks for these files.
+You must edit `gam.cfg` to set the paths you currently use.
+```
+gmail_cse_incert_dir
+        Directory for the S/MIME certificate files used by Gmail Client Side Encryption.
+        Default: Blank
+gmail_cse_inkey_dir
+        Directory for the Key Access Control List (KACL) wrapped private key data files used by Gmail Client Side Encryption.
+        Default: Blank
+```
+
+## Definitions
+* [`<UserTypeEntity>`](Collections-of-Users)
+
+```
+<DomainName> ::= <String>(.<String>)+
+<EmailAddress> ::= <String>@<DomainName>
+<FilePath> ::= <String>
+<Password> ::= <String>
+<KeyPairID> ::= <String>
+```
+## Create Gmail CSE Identity
+Creates and configures a client-side encryption identity that's authorized to send mail from the user account.
+Google publishes the S/MIME certificate to a shared domain-wide directory so that people within a Google Workspace organization can encrypt and send mail to the identity.
+
+```
+gam <UserTypeEntity> create cseidentity <KeyPairID> [kpemail <EmailAddress>]
+        [formatjson]
+```
+If `kpemail <EmailAddress>` is not specified, the user's primary email address is used for the identity.
+
+By default, Gam displays the identity as an indented list of keys and values; the following option causes the output to be in JSON format:
+* `formatjson` - Display the fields in JSON format.
+
+## Update Gmail CSE Identity
+Associates a different key pair with an existing client-side encryption identity. The updated key pair must validate against Google's S/MIME certificate profiles.
+```
+gam <UserTypeEntity> update cseidentity <KeyPairID> [kpemail <EmailAddress>]
+        [formatjson]
+```
+If `kpemail <EmailAddress>` is not specified, the key pair for the user's primary email address is identity updated.
+
+By default, Gam displays the identity as an indented list of keys and values; the following option causes the output to be in JSON format:
+* `formatjson` - Display the fields in JSON format.
+
+## Delete Gmail CSE Identity
+Deletes a client-side encryption identity. The authenticated user can no longer use the identity to send encrypted messages.
+You cannot restore the identity after you delete it. Instead, use the `create cseidentity`  to create another identity with the same configuration.
+
+```
+gam <UserTypeEntity> delete cseidentity [kpemail <EmailAddress>]
+```
+If `kpemail <EmailAddress>` is not specified, the identity for the user's primary email address is deleted.
+
+## Display Gmail CSE Identities
+### Display a client-side encryption identity configuration.
+```
+gam <UserTypeEntity> info cseidentity [kpemail <EmailAddress>]
+        [formatjson]
+```
+If `kpemail <EmailAddress>` is not specified, the user's primary email address is used for the identity.
+
+
+### Display all of the client-side encrypted identities for an authenticated user.
+```
+gam <UserTypeEntity> show cseidentities
+        [formatjson]
+```
+By default, Gam displays the identity as an indented list of keys and values; the following option causes the output to be in JSON format:
+* `formatjson` - Display the fields in JSON format.
+
+```
+gam <UserTypeEntity> print cseidentities [todrive <ToDriveAttribute>*]
+        [formatjson [quotechar <Character>]]
+```
+By default, Gam displays the information as columns of fields; the following option causes the output to be in JSON format:
+* `formatjson` - Display the fields in JSON format.
+
+By default, when writing CSV files, Gam uses a quote character of double quote `"`. The quote character is used to enclose columns that contain
+the quote character itself, the column delimiter (comma by default) and new-line characters. Any quote characters within the column are doubled.
+The `quotechar <Character>` option allows you to choose an alternate quote character, single quote for instance, that makes for readable/processable output.
+`quotechar` defaults to `gam.cfg/csv_output_quote_char`. When uploading CSV files to Google, double quote `"` should be used.
+
+## Create Gmail CSE Key Pair
+Create a CSE Key Pair for the primary address of a user.
+```
+gam <UserTypeEntity> create csekeypair
+        [incertdir <FilePath>] [inkeydir <FilePath>]
+        [addidentity [<Boolean>]] [kpemail <EmailAddress>]
+        [formatjson|returnidonly]
+```
+* The S/MIME certificate files for the users are in the `incertdir <FilePath>` folder/directory.
+* If this option is not specified, the directory is taken from `gam.cfg/gmail_cse_incert_dir`.
+* The files must be named `user@domain.com.p7pem`.
+* The certificate contains the public key and its certificate chain. The chain must be in PKCS#7 format and use PEM encoding and ASCII armor.
+
+* The Key Access Control List (KACL) wrapped private key data files are in the `inkeydir <FilePath>` folder/directory.
+* If this option is not specified, the directory is taken from `gam.cfg/gmail_cse_inkey_dir`.
+* The files must be named `user@domain.com.wrap`.
+* The files are in JSON format with two keys:
+    * `kacls_url` - The URI of the key access control list service that manages the private key.
+    * `wrapped_private_key` - Opaque data generated and used by the key access control list service.
+
+By default, Gam displays the new key pair as an indented list of keys and values; the following options cause the output to be displayed in alternate forms.
+* `formatjson` - Display the fields in JSON format.
+* `returnidonly` - Display just the new `<KeyPairID>`.
+
+If 'addidentity` or `addidentity true` is specified, a client-side encryption identity is created with the new key pair.
+If `kpemail <EmailAddress>` is not specified, the user's primary email address is used for the identity.
+
+By default, Gam displays the identity as an indented list of keys and values; the following option causes the output to be in JSON format:
+* `formatjson` - Display the fields in JSON format.
+* `returnidonly` - Display just the new `<KeyPairID>-<EmailAddress>`.
+
+
+## Action Gmail CSE Key Pairs
+### Disable
+Turns off a client-side encryption key pair. The authenticated user can no longer use the key pair to decrypt incoming CSE message texts or sign outgoing CSE mail.
+```
+gam <UserTypeEntity> disable csekeypair <KeyPairID>
+        [formatjson]
+```
+By default, Gam displays the disabled key pair as an indented list of keys and values; the following option causes the output to be displayed in alternate forms.
+* `formatjson` - Display the fields in JSON format.
+
+### Enable
+Turn on a client-side encryption key pair that was turned off. The key pair becomes active again for any associated client-side encryption identities.
+```
+gam <UserTypeEntity> ensable csekeypair <KeyPairID>
+        [formatjson]
+```
+By default, Gam displays the enabled key pair as an indented list of keys and values; the following option causes the output to be displayed in alternate forms.
+* `formatjson` - Display the fields in JSON format.
+
+### Obliterate
+Delete a client-side encryption key pair permanently and immediately. You can only permanently delete key pairs that have been turned off for more than 30 days.
+To turn off a key pair, use `disable csekeypair`.
+```
+gam <UserTypeEntity> obliterate csekeypair <KeyPairID>
+```
+
+Gmail can't restore or decrypt any messages that were encrypted by an obliterated key. Authenticated users and Google Workspace administrators lose access to reading the encrypted messages.
+
+## Display Gmail CSE Key Pairs
+### Display an existing client-side encryption key pair.
+```
+gam <UserTypeEntity> info csekeypair <KeyPairID>
+        [formatjson]
+```
+By default, Gam displays the key pairs as an indented list of keys and values; the following option causes the output to be in JSON format:
+* `formatjson` - Display the fields in JSON format.
+
+
+### Display all client-side encryption key pairs for an authenticated user.
+```
+gam <UserTypeEntity> show csekeypairs
+        [formatjson]
+```
+By default, Gam displays the key pairs as an indented list of keys and values; the following option causes the output to be in JSON format:
+* `formatjson` - Display the fields in JSON format.
+
+```
+gam <UserTypeEntity> print csekeypairs [todrive <ToDriveAttribute>*]
+        [formatjson [quotechar <Character>]]
+```
+By default, Gam displays the key pairs as columns of fields; the following option causes the output to be in JSON format:
+* `formatjson` - Display the fields in JSON format.
+
+By default, when writing CSV files, Gam uses a quote character of double quote `"`. The quote character is used to enclose columns that contain
