    const gchar *
    as_checksum_kind_to_string (AsChecksumKind kind);

Converts the enumerated value to an text representation.

#### Parameters

kind | the `AsChecksumKind`. |

#### Returns

string version of `kind`

### as_checksum_kind_from_string ()

    AsChecksumKind
    as_checksum_kind_from_string (const gchar *kind_str);

Converts the text representation to an enumerated value.

#### Parameters

kind_str | the string. |

#### Returns

a AsChecksumKind or `AS_CHECKSUM_KIND_NONE` for unknown

### as_checksum_new ()

    AsChecksum *
    as_checksum_new (void);

kind | the AsChecksumKind, e.g. `AS_CHECKSUM_KIND_SHA256`. |

### as_checksum_get_value ()

    const gchar *
    as_checksum_get_value (AsChecksum *cs);

Gets the checksum, usually in its hexadecimal form.

#### Parameters

cs | a AsChecksum instance. |

#### Returns

the checksum.

                           const gchar *value);

Sets the checksum value filename.

#### Parameters

cs | a AsChecksum instance. |
value | the new value. |

## Types and Values

### AS_TYPE_CHECKSUM

    #define AS_TYPE_CHECKSUM (as_checksum_get_type ())
