types
data ASN1Header
ASN1 Header with the class, tag, constructed flag and length.
Constructors
| ASN1Header !ASN1Class !ASN1Tag !Bool !ASN1Length |
Instances
data ASN1Length
ASN1 Length with all different formats
Constructors
| LenShort Int | Short form with only one byte. length has to be < 127. |
| LenLong Int Int | Long form of N bytes |
| LenIndefinite | Length is indefinite expect an EOC in the stream to finish the type |
Instances
data ASN1Event
represent one event from an asn1 data stream
Constructors
| Header ASN1Header | ASN1 Header |
| Primitive !ByteString | Primitive |
| ConstructionBegin | Constructed value start |
| ConstructionEnd | Constructed value end |
parser
parseLBS :: ByteString -> Either ASN1Error [ASN1Event]
Parse one lazy bytestring and returns on success all ASN1 events associated.
parseBS :: ByteString -> Either ASN1Error [ASN1Event]
Parse one strict bytestring and returns on success all ASN1 events associated.
writer
toLazyByteString :: [ASN1Event] -> ByteString
transform a list of ASN1 Events into a lazy bytestring
toByteString :: [ASN1Event] -> ByteString
transform a list of ASN1 Events into a strict bytestring
