/**
* Defines the entries of the SUN provider.
*
* Algorithms supported, and their names:
*
* - SHA is the message digest scheme described in FIPS 180-1.
* Aliases for SHA are SHA-1 and SHA1.
*
* - SHA1withDSA is the signature scheme described in FIPS 186.
* (SHA used in DSA is SHA-1: FIPS 186 with Change No 1.)
* Aliases for SHA1withDSA are DSA, DSS, SHA/DSA, SHA-1/DSA, SHA1/DSA,
* SHAwithDSA, DSAWithSHA1, and the object
* identifier strings "OID.1.3.14.3.2.13", "OID.1.3.14.3.2.27" and
* "OID.1.2.840.10040.4.3".
*
* - SHA-2 is a set of message digest schemes described in FIPS 180-2.
* SHA-2 family of hash functions includes SHA-224, SHA-256, SHA-384,
* and SHA-512.
*
* - SHA-224withDSA/SHA-256withDSA are the signature schemes
* described in FIPS 186-3. The associated object identifiers are
* "OID.2.16.840.1.101.3.4.3.1", and "OID.2.16.840.1.101.3.4.3.2".
* - DSA is the key generation scheme as described in FIPS 186.
* Aliases for DSA include the OID strings "OID.1.3.14.3.2.12"
* and "OID.1.2.840.10040.4.1".
*
* - MD5 is the message digest scheme described in RFC 1321.
* There are no aliases for MD5.
*
* - X.509 is the certificate factory type for X.509 certificates
* and CRLs. Aliases for X.509 are X509.
*
* - PKIX is the certification path validation algorithm described
* in RFC 3280. The ValidationAlgorithm attribute notes the
* specification that this provider implements.
*
* - LDAP is the CertStore type for LDAP repositories. The
* LDAPSchema attribute notes the specification defining the
* schema that this provider uses to find certificates and CRLs.
*
* - JavaPolicy is the default file-based Policy type.
*
* - JavaLoginConfig is the default file-based LoginModule Configuration type.
