/**
 * 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".
 *
 * - 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.
