codec.pkcs8.PrivateKeyInfo

sa.com/rsalabs/pubs/PKCS/html/pkcs-8.html"> PKCS#8. The ASN.1 definition of this structure is

 PrivateKeyInfo ::= SEQUENCE ( version Version,  -- 0 for version 1.2 Nov 93 privateKeyAlgorithm PrivateKeyAlgorithmIdentifier, privateKey PrivateKey, attributes [0] IMPLICIT Attributes OPTIONAL } Version ::= INTEGER PrivateKeyAlgorithmIdentifier ::= AlgorithmIdentifier PrivateKey ::= OCTET STRING Attributes ::= SET OF Attribute

The following definitions are taken from the X501 standard:

 Attribute ::= SEQUENCE { type AttributeType values SET OF AttributeValue -- at least one value is required -- } AttributeType ::= OBJECT IDENTIFIER AttributeValue ::= ANY

Helper class (POI) which holds private key and the assigned certificates. @author Josef Cacek
org.apache.geronimo.crypto.asn1.pkcs.PrivateKeyInfo
org.apache.geronimo.util.asn1.pkcs.PrivateKeyInfo
org.apache.harmony.security.pkcs8.PrivateKeyInfo
The class implements the ASN.1 DER encoding and decoding of the PKCS#8 PrivateKeyInfo having the following ASN.1 notation: PrivateKeyInfo ::= SEQUENCE { version Version, privateKeyAlgorithm PrivateKeyAlgorithmIdentifier, privateKey PrivateKey, attributes [0] IMPLICIT Attributes OPTIONAL } Version ::= INTEGER PrivateKeyAlgorithmIdentifier ::= AlgorithmIdentifier PrivateKey ::= OCTET STRING Attributes ::= SET OF Attribute
