Method Details

engineGeneratePrivate
Converts, if possible, a key specification into aBCRainbowPrivateKey
. Currently, the following key specifications are supported:RainbowPrivateKeySpec
,PKCS8EncodedKeySpec
.The ASN.1 definition of the key structure is
RainbowPrivateKey ::= SEQUENCE { oid OBJECT IDENTIFIER -- OID identifying the algorithm A1inv SEQUENCE OF OCTET STRING -- inversed matrix of L1 b1 OCTET STRING -- translation vector of L1 A2inv SEQUENCE OF OCTET STRING -- inversed matrix of L2 b2 OCTET STRING -- translation vector of L2 vi OCTET STRING -- num of elmts in each Set S layers SEQUENCE OF Layer -- layers of F } Layer ::= SEQUENCE OF Poly Poly ::= SEQUENCE { alpha SEQUENCE OF OCTET STRING beta SEQUENCE OF OCTET STRING gamma OCTET STRING eta OCTET }
- Specified by:
engineGeneratePrivate
in classKeyFactorySpi
- Parameters:
keySpec
- the key specification- Returns:
- the Rainbow private key
- Throws:
InvalidKeySpecException
- if the KeySpec is not supported.
-
engineGeneratePublic
Converts, if possible, a key specification into aBCRainbowPublicKey
. Currently, the following key specifications are supported:X509EncodedKeySpec
.The ASN.1 definition of a public key's structure is
RainbowPublicKey ::= SEQUENCE { oid OBJECT IDENTIFIER -- OID identifying the algorithm docLength Integer -- length of signable msg coeffquadratic SEQUENCE OF OCTET STRING -- quadratic (mixed) coefficients coeffsingular SEQUENCE OF OCTET STRING -- singular coefficients coeffscalar OCTET STRING -- scalar coefficients }
- Specified by:
engineGeneratePublic
in classKeyFactorySpi
- Parameters:
keySpec
- the key specification- Returns:
- the Rainbow public key
- Throws:
InvalidKeySpecException
- if the KeySpec is not supported.
-
engineGetKeySpec
Converts a given key into a key specification, if possible. Currently the following specs are supported:- for RainbowPublicKey: X509EncodedKeySpec, RainbowPublicKeySpec
- for RainbowPrivateKey: PKCS8EncodedKeySpec, RainbowPrivateKeySpec
- Specified by:
engineGetKeySpec
in classKeyFactorySpi
- Parameters:
key
- the keykeySpec
- the key specification- Returns:
- the specification of the CMSS key
- Throws:
InvalidKeySpecException
- if the key type or key specification is not supported.
-
engineTranslateKey
Translates a key into a form known by the FlexiProvider. Currently the following key types are supported: RainbowPrivateKey, RainbowPublicKey.- Specified by:
engineTranslateKey
in classKeyFactorySpi
- Parameters:
key
- the key- Returns:
- a key of a known key type
- Throws:
InvalidKeyException
