In a software all the crypto needs can be put in to two categories. The component which deals with data encryption and decryption for internal usage. The component which deals with the signing, signature validation, encryption, decryption when working with external entities.

One of the main purposes of the crypto service is to provide a developer friendly API to handle cryptography in Carbon product. The crypto context helps the developers to write the context specific logic e. Finding the public key of the external party for validating the signature once is re-use it by just passing the context for operation.

In external crypto scenarios the keys of the external entities i. Databases, KeyStores. Key resolver chains find the applicable key information based on the crypto context. The default internal crypto provider is based on asymmetric cryptography due to historical reasons. This implementation reads the needed Java KeyStore information from a configuration file.

More details can be found in the How to use section. The crypto service ships a symmetric key based internal crypto provider as well. But it is not the default implementation. The crypto service doesn't ship a default external crypto provider. The external crypto operations in Carbon products should deal with the complexity behind tenant key stores etc. Therefore the Carbon Kernel ships an implementation to be used in Carbon products. For the sake of completeness that implementation also will be mentioned in this documentation whenever needed.

A context independent key resolver is shipped to be used as the last resort to resolve the needed key information for the given context. Since the key resolvers has a priority mechanism, if an applicable resolver is found for a context, the default resolver won't be used. Below is the default configuration block for the crypto service. All the available operations of the API are documented here. Implement InternalCryptoProvider.

Implement ExternalCryptoProvider. Implement KeyResolver. Implement CryptoService. Skip to content. Star 0. License Apache These different groups are known as "operations" in OpenSSL.

Each operation has a different set of functions associated with it. A provider in OpenSSL is a component that collects together algorithm implementations. In order to use an algorithm you must have at least one provider loaded that contains an implementation of it.

OpenSSL comes with a number of providers and they may also be obtained from third parties. If you don't load a provider explicitly either in program code or via config then the OpenSSL built-in "default" provider will be automatically loaded.

A library context can be thought of as a "scope" within which configuration options take effect. When a provider is loaded, it is only loaded within the scope of a given library context.

In this way it is possible for different components of a complex application to each use a different library context and have different providers loaded with different configuration settings. If an application does not explicitly create a library context then the "default" library context will be used. Applications can always pass NULL for this parameter to just use the default library context. The default library context is automatically created the first time it is needed.

This will automatically load any available configuration file and will initialise OpenSSL for use. Unlike in earlier versions of OpenSSL prior to 1. Similarly when the application exits the default library context is automatically destroyed. No explicit de-initialisation steps need to be taken. As long as OpenSSL has been built with support for threads the default case on most platforms then most OpenSSL functions are thread-safe in the sense that it is safe to call the same function from multiple threads at the same time.

However most OpenSSL data structures are not thread-safe. There are exceptions to these rules. A small number of functions are not thread safe at all. Where this is the case this restriction should be noted in the documentation for the function.

Similarly some data structures may be partially or fully thread safe. See openssl-threads 7 for a more detailed discussion on OpenSSL threading support. In order to use an algorithm an implementation for it must first be "fetched". Fetching is the process of looking through the available implementations, applying selection criteria via a property query string , and finally choosing the implementation that will be used.

When fetching an algorithm it is possible to specify a property query string to guide the selection process.

Property query strings can be specified explicitly as an argument to a function. Where both default properties and function specific properties are specified then they are combined. Function specific properties will override default properties where there is a conflict. Users of the OpenSSL libraries never query a provider directly for an algorithm implementation.

Instead, the diverse OpenSSL APIs often have explicit fetching functions that do the work, and they return an appropriate algorithm object back to the user. This may be NULL to signify the default global library context, or a context created by the user. The algorithm implementation that is fetched can then be used with other diverse functions that use them.

These are present for compatibility with OpenSSL before version 3. In some cases implicit fetching can also occur when a NULL algorithm parameter is supplied. In this case an algorithm implementation is implicitly fetched using default search criteria and an algorithm name that is consistent with the context in which it is being used. Fetch any available implementation of SHA in the default context. Note that some algorithms have aliases. Fetch an implementation of SHA that is not from the default provider in the default context:.

Also note that the default provider should be explicitly loaded if it is required in addition to other providers:. The algorithms available in each of these providers may vary due to build time configuration options. The openssl-list 1 command can be used to list the currently available algorithms.

The names of the algorithms shown from openssl-list 1 can be used as an algorithm identifier to the appropriate fetching function. Also see the provider specific manual pages linked below for further details about using the algorithms available in each of the providers. As well as the OpenSSL providers third parties can also implement providers.

For information on writing a provider see provider 7. The default provider is built in as part of the libcrypto library and contains all of the most commonly used algorithm implementations. The default provider includes all of the functionality in the base provider below. If you don't load any providers at all then the "default" provider will be automatically loaded. If you explicitly load any provider then the "default" provider would also need to be explicitly loaded if it is required.

The base provider is built in as part of the libcrypto library and contains algorithm implementations for encoding and decoding for OpenSSL keys. The FIPS provider is a dynamically loadable module, and must therefore be loaded explicitly, either in code or through OpenSSL configuration see config 5.

It contains algorithm implementations that have been validated according to the FIPS standard. The legacy provider is a dynamically loadable module, and must therefore be loaded explicitly, either in code or through OpenSSL configuration see config 5.
