gnutls_ciphersuite_get - Linux
Overview
The gnutls_ciphersuite_get
command retrieves the cipher suite being used in a GNU TLS connection. It provides detailed information about the cipher suite, including its name, encryption and integrity algorithms, and other relevant parameters.
Syntax
gnutls_ciphersuite_get [OPTIONS] SESSION
Options/Flags
-h
,--help
: Display help information and exit.--version
: Print version information and exit.-v
,--verbose
: Enable verbose output, providing more detailed information about the cipher suite.-n
,--no-names
: Do not display cipher suite names in the output.-a
,--all
: List all available cipher suites, regardless of whether they are supported by the connection.
Examples
Simple usage:
gnutls_ciphersuite_get session-id
Verbose output:
gnutls_ciphersuite_get -v session-id
Listing all available cipher suites:
gnutls_ciphersuite_get --all
Common Issues
- Incorrect session ID: Ensure that the provided session ID is valid and corresponds to an active GNU TLS connection.
- Permission denied: Verify that the user has sufficient permissions to access the session information.
Integration
gnutls_ciphersuite_get
can be integrated into scripts or command chains to retrieve and analyze cipher suite information in automated tasks. For example:
session_id=$(gnutls_session_get_id)
cipher_suite=$(gnutls_ciphersuite_get -n $session_id)
echo "The cipher suite in use is: $cipher_suite"
