    readEntriesFromCsv(InputStream csvInputStream, Function<org.apache.commons.csv.CSVRecord,T> recordMapper)
    Reads entries from a CSV input stream, processes each record using a provided mapper function, and returns a list of mapped entries
    static void
    sortCsv(Path csvFilePath, Supplier<Comparator<String[]>> comparatorSupplier)
    Reads a CSV file, sorts its data based on a supplied comparator, and writes the sorted data back to the file.
    static void
    sortCsvByAlgorithmAndKeysize(Path csvFilePath)
    Reads a CSV file, sorts its data by 'algorithm' and 'keysize' in ascending order, and writes the sorted data back to the file
    static void
    sortCsvByKeypairAndSignatureAlgorithm(Path csvFilePath)
    Sorts a CSV file by 'keypair-algorithm' and 'signature-algorithm', removes duplicates, and rewrites the sorted data back to the CSV file
