CadesSignatureCompression

Namespace: Lacuna.Pki.Cades
Assembly: Lacuna.Pki
Class

Class with methods for compressing and decompressing CAdES signatures storing objects likely to be repeated across different signatures such as certificates and CRLs on an external store, avoiding redundant storage of such objects.

public static class CadesSignatureCompression

Hierarquia: object → CadesSignatureCompression

Métodos

Compress(byte[], ISimpleStore, out byte[])

Compresses a CAdES signature storing objects likely to be repeated across different signatures such as certificates and CRLs in an external store, separating the encapsulated content within the signature (attached signature) if present.

public static byte[] Compress(byte[] cadesSignature, ISimpleStore store, out byte[] encapsulatedContent)

Parâmetros

Nome	Tipo	Descrição
cadesSignature	byte[]	The CAdES signature to be compressed.
store	ISimpleStore	The external store on which to store the repeatable objects.
encapsulatedContent	byte[]	When this method returns, contains the encapsulated content within the signature, if any.

Retorno

byte[] — The compressed signature in a proprietary format that can be decompressed with the Byte%5b%5d) method.

Comentários

The given signature need not have been generated by the SDK, it can be any CAdES signature.

If you wish to store the signature with the encapsulated content inside, or if you don´t care about the encapsulated content (for instance if all your signatures are detached), use the method ISimpleStore) instead.

Compress(byte[], ISimpleStore)

Compresses a CAdES signature storing objects likely to be repeated across different signatures such as certificates and CRLs in an external store.

public static byte[] Compress(byte[] cadesSignature, ISimpleStore store)

Parâmetros

Nome	Tipo	Descrição
cadesSignature	byte[]	The CAdES signature to be compressed.
store	ISimpleStore	The external store on which to store the repeatable objects.

Retorno

byte[] — The compressed signature in a proprietary format that can be decompressed with the Byte%5b%5d) method.

Comentários

The given signature need not have been generated by the SDK, it can be any CAdES signature.

If the given signature has an encapsulated content (attached signature), this method does not remove it. If you want to separate the encapsulated content from the signature during the compression, use the method Byte%5b%5d%40) instead.

---

Decompress(byte[], ISimpleStore, byte[])

Decompresses a CAdES signature previously compressed with the compression methods from this class.

public static byte[] Decompress(byte[] compressedSignature, ISimpleStore store, byte[] encapsulatedContent)

Parâmetros

Nome	Tipo	Descrição
compressedSignature	byte[]	The compressed signature in proprietary format.
store	ISimpleStore	The external store where the repeatable objects were stored during the compression.
encapsulatedContent	byte[]	The encapsulated content separated during the compression, if any.

Retorno

byte[] — The original signature.

Comentários

If the original signature had an encapsulated content and the method Byte%5b%5d%40) was used to compress the signature, you must pass the encapsulatedContent parameter.

---

Decompress(byte[], ISimpleStore)

Decompresses a CAdES signature previously compressed with the compression methods from this class.

public static byte[] Decompress(byte[] compressedSignature, ISimpleStore store)

Parâmetros

Nome	Tipo	Descrição
compressedSignature	byte[]	The compressed signature in proprietary format.
store	ISimpleStore	The external store where the repeatable objects were stored during the compression.

Retorno

byte[]
