AI-generated Key Takeaways
-
PKCS8EncodedKeySpec
represents the ASN.1 encoding of a private key, based on the PKCS#8 standard'sPrivateKeyInfo
structure. -
It provides access to the encoded key bytes and the encoding format, which is "PKCS#8".
-
This class is used in conjunction with
KeyFactory
to convert the encoded key into a usable private key object. -
A new
PKCS8EncodedKeySpec
is created using the encoded private key bytes, which are copied to ensure immutability.
This class represents the ASN.1 encoding of a private key,
encoded according to the ASN.1 type PrivateKeyInfo
.
The PrivateKeyInfo
syntax is defined in the PKCS#8 standard
as follows:
PrivateKeyInfo ::= SEQUENCE { version Version, privateKeyAlgorithm PrivateKeyAlgorithmIdentifier, privateKey PrivateKey, attributes [0] IMPLICIT Attributes OPTIONAL } Version ::= INTEGER PrivateKeyAlgorithmIdentifier ::= AlgorithmIdentifier PrivateKey ::= OCTET STRING Attributes ::= SET OF Attribute
