Only java.exe executables that are digitally signed will be executed to gather additional details about the Java version that are required for assessing Oracle Java license requirements. File evidence will still be reported for java.exe executables that are not digitally signed, but the executables will not be executed to obtain version information, nor will additional Java verification checks be performed.

DROID is a software tool developed by The National Archives to perform automated batch identification of file formats. Developed by our Digital Preservation department as part of its broader digital preservation activities, DROID is designed to meet the fundamental requirement of any digital repository to be able to identify the precise format of all stored digital objects, and to link that identification to a central registry of technical information about that format and its dependencies.

DROID uses internal signatures to identify and report the specific file format and version of digital files. These signatures are stored in an XML signature file, generated from information recorded in the PRONOM technical registry. New and updated signatures are regularly added to PRONOM, and DROID can be configured to automatically download updated signature files.

DROID 6.5 onwards provides two download options for users. The first is embedded with Java OpenJDK 11 for Windows users and does not require Java to be installed to run. The second can be run on any system with Java 8 to 11 installed.

User support is available from our Google Groups discussion page, ideal for questions about DROID, or assistance getting DROID working. Alternatively you can contact us via email. Bug reports, feature requests, and code contributions should be raised through GitHub Issues. We welcome contributions of new formats and format signatures to the PRONOM registry. If you wish to contribute, please use our online form. Signature Files and their release notes can be found below:

DroidConvert transforms a DROID CSV export into the structure required for digital transfers to The National Archives. This is for use by Public Record bodies preparing digital collections for transfer. The Readme included within the download contains information on using this tool.

Jsign is a versatile code signing tool that allows you to sign and timestampWindows executable files, installer packages and scripts. Jsign is platformindependent and provides an alternative to native tools like signtool on Windowsor the Mono development tools on Unix systems. It's particularly well-suited forsigning executable wrappers and installers generated by tools such asNSIS, msitools,install4j,exe4jor launch4j. It emphasizes on seamlessintegration with cloud key management systems and hardware tokens.

The sign command is used by default, but other commands can be specified with the commandattribute. For example for tagging a signed file with user identification data withoutinvalidating the signature:

After the options Jsign accepts one or more files to sign as arguments. The arguments may contain '*'or '**' wildcards to match multiple files and scan through directories recursively. For example usingbuild/*.exe will sign the executables in the build directory, and installdir/**/*.dll willscan the installdir directory recursively and sign all the DLLs found. If an argument starts with @ it is consideredas a text file containing a list of files to sign, one per line.

When using a Yubikey, the alias is required only if the device contains more than one certificate.The certificate is specified by its name (typically X.509 Certificate for Digital Signature forthe slot 9c, or X.509 Certificate for PIV Authentication for the slot 9a). The ykcs11 libraryfrom the Yubico PIV Tool mustbe installed on the system at the default location.

Other Nitrokeys based on the OpenPGP card standard are also supported with this storetype, but an X.509 certificatemust be imported into the Nitrokey (using the gnupg writecertcommand). Keys without certificates are ignored. Alternatively, the OPENPGP storetype can also be used, it doesn'trequire OpenSC and any key can be used by providing an external certificate.

OpenPGP cards contain up to 3 keys, one for signing, one for encryption, and one for authentication. All of themcan be used for code signing (except encryption keys based on an elliptic curve). The alias to select the key is either,SIGNATURE, ENCRYPTION or AUTHENTICATION. The OPENPGP storetype can be used witha Nitrokey (non-HSM models) or a Yubikey.

PIV cards contain up to 24 keys and certificates. The alias to select the key is either AUTHENTICATION,SIGNATURE, KEY_MANAGEMENT, CARD_AUTHENTICATION, or RETIRED.Slot numbers are also accepted (for example 9c for the digital signature key). jsign --storetype PIV --storepass 123456 --alias SIGNATURE application.exeIf multiple devices are connected, the keystore parameter can be used to specifythe name of the one to use.

The AWS access key, secret key, and optionally the session token, are concatenatedand used as the storepass parameter; if the latter is not provided, Jsign attempts to fetch the credentialsfrom the environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY and AWS_SESSION_TOKEN)or from the IMDSv2 servicewhen running on an AWS EC2 instance.

With the Azure Trusted Signing servicethe keystore parameter specifies the endpoint URI, and the alias combines the account name andthe certificate profile. The Azure API access token is used as the keystore password.

The certificates issued by Azure Trusted Signing have a lifetime of 3 days only, and timestamping is necessary toensure the long term validity of the signature. For this reason timestamping is automatically enabled when signingwith this service.

Implementation note: Jsign performs an extra call to the signing API to retrieve the current certificate chain beforesigning. When signing multiple files it's recommended to invoke Jsign only once with the list of files to avoid doublingthe quota usage.

Certificates and keys stored in the DigiCert ONE Secure Software Managercan be used directly without installing the DigiCert client tools. It requires an API key and a PKCS#12 keystore holdinga client certificate for the authentication. The US DigiCert ONE host is used by default ( )but a different host can be specified with the --keystore parameter.

GaraSign is a remote signing service provided by Garantir.The authentication is performed by specifying the username/password or the TLS client certificate in thestorepass parameter. If the TLS client certificate is stored in a password protected keystore,the password is specified in the keypass parameter. The keystore parameter referencesthe URL of the GaraSign REST API ( :8443/CodeSigningRestService/ by default).

Google Cloud KMS stores only the private key, the certificate must be provided separately. The keystore parameterreferences the path of the keyring. The alias specifies the name and the version of the key:

The version of the key can be omitted (e.g. --alias test), in this case the most recent versionof the key is picked automatically. This avoids modifying the parameters every time the key is updated, but the signingprocess is slightly slower due to an additional API call, and it requires an extra permission.

When creating the key the purpose must be set to "Asymmetric sign", and the algorithm must be either Elliptic Curveor RSA with PKCS#1 v1.5 padding and SHA digest. Keys with PSS padding or raw RSA mode are not supported.

HashiCorp Vault exposes keys through secrets engines. Jsignsupports the Google Cloud KMS andTransit secrets engines. The keystoreparameter references the endpoint of the secrets engine, which is typically the Vault server URL and the API versionv1 followed by the secrets engine path. The certificate must be provided separately using thecertfile parameter. The alias parameter specifies the name of the key in Vault. For theGoogle Cloud KMS secrets engine, the version of the Google Cloud key is appended to the key name, separated by a coloncharacter.

Signing with the Oracle Cloud Infrastructure Key Management Service requires theconfiguration file or theenvironment variablesused by the OCI CLI. The OCI CLI isn't required for signing, but it may be used to initialize the configuration filewith oci setup bootstrap.

A signed file can be modified to include additional data without invalidating the signature. This feature is usefulfor embedding user identification data, such as a licence key or a session token, within a signed installer when thefile is downloaded. Upon installation, the installer extracts this data, enabling the application to automaticallyauthenticate the user without requiring credentials.

A common pattern consist in embedding a default template at build time, providing enough space for the datato be inserted when the file is downloaded. This allows a simple search-and-replace operation to be performedon the download server without needing Jsign to be installed. For example:

Jsign leverages the cryptography API developed by the Bouncy Castle project.
PVK parsing is based on the pvktool by Stephen N Henson.
MSI signing was possible thanks to the work done by the osslsigncode and Apache POI projects.

Jsign includes contributions from Emmanuel Bourg, Florent Daigniere, Michael Szediwy, Michael Peterson, Markus Kils,Erwin Tratar, Bjrn Kautler, Joseph Lee, Maria Merkel, Vincent Malmedy, Sebastian Stamm and Eatay Mizrachi.

Support for SHA-2 was introduced in OpenSSL 0.9.8, but is not enabled by default with SSL_library_init(). In 0.9.8, SHA-2 hash functions must be called specifically or by using OpenSSL_add_all_algorithms() which may not be desired. OpenSSL 0.9.8o enables the SHA-2 hash algorithms in the default configuration. Database Support

* The pgcrypto module for PostgreSQL introduced support for the SHA-2 family of hash algorithms with the 8.1 release but only for the standalone module. 8.2 incorporated the SHA-2 functions of the pgcrypto module into PostgreSQL core allowing these hashes to be available to PostgreSQL even if the installed version of OpenSSL does not support it.
