For fully supporting the OSCCA-approved cryptography algorithm, FISCO integrates the national encryption, decryption, signature, verification, hash algorithm and SSL communication protocol in the FISCO BCOS platform based on the OSCCA-approved cryptography standard. The design documents can be found in the FISCO BCOS Design Manual. OSCCA-approved cryptography Version.
Initial deployment of FISCO BCOS OSCCA-approved cryptography version¶
This section uses the build_chain script to build a 4-nodes FISCO BCOS chain locally, and uses
Ubuntu 16.04 system as an example to operate. This section uses pre-compiled static
fisco-bcos binaries for testing on CentOS 7 and Ubuntu 16.04.
# rely on the installation of Ubuntu16 $ sudo apt install -y openssl curl # prepare environment $ cd ~ && mkdir -p fisco && cd fisco # download build_chain.sh script $ curl -#LO https://github.com/FISCO-BCOS/FISCO-BCOS/releases/download/v2.7.2/build_chain.sh # If you have network issue for exec command above, please try: $ curl -#LO https://gitee.com/FISCO-BCOS/FISCO-BCOS/raw/master-2.0/tools/build_chain.sh $ chmod u+x build_chain.sh
build a 4-nodes FISCO BCOS chain
# Generate a 4-nodes FISCO chain. All nodes belong to group1. The following instructions are executed in the fisco directory. # -p specifies the starting ports which are p2p_port, channel_port, jsonrpc_port # According to the following instructions, it needs to ensure that the 30300~30303, 20200~20203, 8545~8548 ports of the machine are not occupied. # -g It will generate a chain of OSCCA-approved cryptography. $ ./build_chain.sh -l 127.0.0.1:4 -p 30300,20200,8545 -g
build_chain.sh script option, please [refer to here] (../manual/build_chain.md). The command that execute normally will output
All completed. (If there is no output, refer to
nodes/build.log for checking).

After the deployment of the OSCCA-approved cryptography alliance chain is completed, the rest of operations are same as [installation] (../installation.md).
OSCCA-approved cryptography configuration information¶
The nodes of FISCO BCOS OSCCA-approved cryptography version message through using SSL secure channel. The main configuration items of the SSL certificate are concentrated in the following configuration items:
[network_security] data_path：path where the certificate file is located key：the path of the node private key relative to the data_path cert: the path of the certificate gmnode.crt relative to data_path ca_cert: the path of certificate gmca ;certificate configuration [network_security] ;directory the certificates located in data_path=conf/ ;the node private key file key=gmnode.key ;the node certificate file cert=gmnode.crt ;the ca certificate file ca_cert=gmca.crt
After Fisco-BCOS version 2.5.0, nodes and SDKS can communicate using either SSL or national secret SSL connections. The configuration is as follows:
[chain] ; use SM crypto or not, should nerver be changed sm_crypto=true ; use SM SSL connection with SDK sm_crypto_channel=true
using OSCCA-approved cryptography SDK¶
For details, refer to [SDK Documentation] (../sdk/sdk.html#id8).
OSCCA-approved cryptography console configuration¶
using OSCCA-approved cryptography console¶
The function of OSCCA-approved cryptography console is used in the same way as the standard console. Console version 2.6 and above does not require additional configuration. For the configuration method of console version 1.x, please refer to Console Operation Manual.
OSCCA-approved cryptography configuration¶
OSCCA-approved cryptography Key Manager¶
Other steps are same as the standard Key Manager. Please refer to key-manager repository.
OSCCA-approved cryptography node configuration¶
FISCO BCOS OSCCA-approved cryptography version adopts dual certificate mode, so two sets of certificates are needed for disk encryption. They are the conf/gmnode.key and conf/origin_cert/node.key. Other operations of disk encryption are the same as [Standard Edition Loading Encryption Operation] (./storage_security.md).
