Cryptographic Provider
The Keeper Secrets Manager SDK expects the developer to use their required cryptographic provider. As documented above, Keeper will use the default cryptographic module of the Java runtime unless a specific provider is added. In the examples here in this documentation, we are using the BouncyCastle FIPS provider.
In the source code, ensure that the provider is loaded in the security context:
fun main() {
Security.addProvider(BouncyCastleFipsProvider())
...
See the file CryptoUtilsTest.kt
as shown in this example on how to use a custom security provider.

Security.addProvider(new BouncyCastleFipsProvider());
try {
initializeStorage(storage, oneTimeToken);

Retrieve Values From a Secret
Retrieve a Password
This shortcut gets the password of a secret once that secret has been retrieved from Keeper Secrets Manager.
secret.getPassword()
Retrieve Fields
secret.getData().getField(<FIELD_TYPE>)
To get a field value, you will need to cast the return to the class of the corresponding field type. For a list of field types see the Record Types page.
Keeper Notation
Notation.getValue(secret, "<query>");
// Query example "<RECORD UID>/field/login"
Parameter
Type
Required
Default
Description
secret
KeeperRecord
Yes
Record to get field value from
query
String
Yes
Dot notation query of desired field
Get TOTP Code
TotpCode.uriToTotpCode(url)
Parameter
Type
Required
Default
Description
url
String
Yes
TOTP Url
Update Values in a Secret
Record update commands don't update local record data on success (esp. updated record revision) so any consecutive updates to an already updated record will fail due to revision mismatch. Make sure to reload all updated records after each update batch.
Update Secret
updateSecret(options: SecretsManagerOptions, recordToUpdate: KeeperRecord);
Update Secret is used to save changes made to a secret. Once updateSecret is performed successfully, the changes are reflected in the Keeper Vault.
Parameter
Type
Required
Default
Description
options
SecretsManagerOptions
Yes
Storage and query configuration
recordToUpdate
KeeperRecord
Yes
Record to update
Update Password
recordToUpdate.updatePassword(password: String);
SecretsManager.updateSecret(options, recordToUpdate);
Parameter
Type
Required
Default
Description
password
String
Yes
New password to set
Update other fields
//format
RecordField.getValue().set(index, value)
//example - Login field
recordLogin.getValue().set(0, "New Login");
Each record field type is represented by a class. Cast the field to the corresponding class in order to correctly access the field's value. Check the Record Types documentation for a list of field types.
Fields can have multiple values, which is accessed in a List. In this example we are updating the login field, which only accepts one value, so we update the one value in the values list.
Generate a Random Password
generatePassword(length: int, lowercase: int, uppercase: int, digits: int, specialCharacters: int)
length
int
Optional
64
lowercase
int
Optional

Create a Secret
Prerequisites:
Shared folder UID
Shared folder must be accessible by the Secrets Manager Application
You and the Secrets Manager application must have edit permission
There must be at least one record in the shared folder
Created records and record fields must be formatted correctly
See the documentation for expected field formats for each record type
TOTP fields accept only URL generated outside of the KSM SDK
After record creation, you can upload file attachments using uploadFile
SecretsManager.createSecret(options, folderUid, newRecordData, secrets);
options
SecretsManagerOptions
Yes
folderUid
String
Yes
newRecordData
KeeperRecordData
Yes
secrets
KeeperSecrets
Optional
Freshly fetched list of all secrets from the Keeper servers
Delete a Secret
The Java/Kotlin KSM SDK can delete records in the Keeper Vault.
deleteSecret(smOptions, recordUids);
smOptions
SecretsManagerOptions
Yes
recordUids
List<Sting>
Yes
Caching
To protect against losing access to your secrets when network access is lost, the Java SDK allows caching of secrets to the local machine in an encrypted file.
Setup and Configure Cache
In order to setup caching in the Java SDK, include a caching post function as the second argument when instantiating aSecretsManagerOptions
object.
The Java SDK includes a default caching function cachingPostFunction
which stores cached queries to a file.
//create options with caching
SecretsManagerOptions options = new SecretsManagerOptions(storage, SecretsManager::cachingPostFunction);
//example get all secrets
SecretsManager.getSecrets(options)
Folders
Folders have full CRUD support - create, read, update and delete operations.

SecretsManagerOptions options = new SecretsManagerOptions(new LocalConfigStorage("ksm-config.json"));
List<KeeperFolder> folders = SecretsManager.getFolders(options);
Create a Folder
Requires CreateOptions
and folder name to be provided. The folder UID parameter in CreateOptions
is required - UID of a shared folder, while sub-folder UID is optional and if missing new regular folder is created directly under the parent (shared folder). There's no requirement for the sub-folder to be a direct descendant of the parent shared folder - it could be many levels deep.
