class ProposalParser:
    """A class to parse IKE and ESP proposal strings into human-readable formats.

    This class supports parsing of IKE and ESP proposals, extracting encryption, hash, PRF (for IKE),
    and Diffie-Hellman (DH) group information. It also handles the concatenation of these components
    into a structured format, indicating whether Perfect Forward Secrecy (PFS) is enabled for ESP proposals.
    The parser uses predefined mappings for DH groups, encryption algorithms, hash functions, and Pseudo-Random Functions (PRFs).
    It can process a list of proposals and return a formatted string summarizing the cryptographic parameters.
    Attributes:

        dh_mapping (dict): A mapping of Diffie-Hellman groups to their corresponding identifiers

        enc_mapping (dict): A mapping of encryption algorithms to their corresponding identifiers

        hash_mapping (dict): A mapping of hash functions to their corresponding identifiers

        prf_mapping (dict): A mapping of Pseudo-Random Functions to their corresponding identifiers

    Methods:
        parse_ike_proposal(proposal): Parses a single IKE or ESP proposal string into a structured dictionary with encryption, hash, PRF, and DH group information.

        process_proposals(proposal_list): Processes a comma-separated list of IKE or ESP proposals, concatenating encryption, hash, PRF (for IKE), and DH group values, and indicating whether PFS is enabled for ESP proposals.
    
    Usage:
        _proposal_parser = ProposalParser()
        proposal = "IKE:AES_CBC_256/HMAC_SHA2_256/PRF_HMAC_SHA2_256/MODP_2048"
