In seahorse, libcryptui/cryptui.h there's an enum:

/**
 * CryptUIEncType:
 * @CRYPTUI_ENCTYPE_NONE: the key is none of the below types
 * @CRYPTUI_ENCTYPE_SYMMETRIC: the key's type is symmetric
 * @CRYPTUI_ENCTYPE_PUBLIC: the key's type is public
 * @CRYPTUI_ENCTYPE_PRIVATE: the key's type is private
 * @_CRYPTUI_ENCTYPE_MAXVALUE: for internal use only
 *
 * Used in key properties to indicate what kind of key it is
 *
 * Never ever change a values already present. These values are used
 * across applications, DBus etc... 
 */
typedef enum {
    CRYPTUI_ENCTYPE_NONE =       0,
    CRYPTUI_ENCTYPE_SYMMETRIC =  1,
    CRYPTUI_ENCTYPE_PUBLIC =     2,
    CRYPTUI_ENCTYPE_PRIVATE =    3,
    
    /* Used internally */
    _CRYPTUI_ENCTYPE_MAXVALUE
} CryptUIEncType;

That gets scanned and placed into the gir file as:

<enumeration name="EncType"
                 doc="Used in key properties to indicate what kind of key it is
Never ever change a values already present. These values are used
across applications, DBus etc..."
                 c:type="CryptUIEncType">
      <member name="ryptui_enctype_none"
              value="0"
              c:identifier="CRYPTUI_ENCTYPE_NONE"/>
      <member name="ryptui_enctype_symmetric"
              value="1"
              c:identifier="CRYPTUI_ENCTYPE_SYMMETRIC"/>
      <member name="ryptui_enctype_public"
              value="2"
              c:identifier="CRYPTUI_ENCTYPE_PUBLIC"/>
      <member name="ryptui_enctype_private"
              value="3"
              c:identifier="CRYPTUI_ENCTYPE_PRIVATE"/>
      <member name="cryptui_enctype_maxvalue"
              value="4"
              c:identifier="_CRYPTUI_ENCTYPE_MAXVALUE"/>
    </enumeration>

The member names are wrong.  The patch for seahorse hasn't been committed yet.
