The term 35# "provider" refers to a package or set of packages that supply a 36# concrete implementation of a subset of the cryptography aspects of 37# the Java Security API. A provider may, for example, implement one or 38# more digital signature algorithms or message digest algorithms. 39# 40# Each provider must implement a subclass of the Provider class. 41# To register a provider in this master security properties file, 42# specify the provider and priority in the format 43# 44# security.provider.<n>=<provName | className> 45# 46# This declares a provider, and specifies its preference 47# order n. The preference order is the order in which providers are 48# searched for requested algorithms (when no specific provider is 49# requested). The order is 1-based; 1 is the most preferred, followed 50# by 2, and so on. 51# 52# <provName> must specify the name of the Provider as passed to its super 53# class java.security.Provider constructor. This is for providers loaded 54# through the ServiceLoader mechanism. 55# 56# <className> must specify the subclass of the Provider class whose 57# constructor sets the values of various properties that are required 58# for the Java Security API to look up the algorithms or other 59# facilities implemented by the provider. This is for providers loaded 60# through classpath. 61# 62# Note: Providers can be dynamically registered instead by calls to 63# either the addProvider or insertProviderAt method in the Security 64# class. 65 66# 67# List of providers and their preference orders (see above): 68# 69security.provider.1=SUN 70security.provider.2=SunRsaSign 71security.provider.3=SunEC 72security.provider.4=SunJSSE 73security.provider.5=SunJCE 74security.provider.6=SunJGSS 75security.provider.7=SunSASL 76security.provider.8=XMLDSig 77security.provider.9=SunPCSC 78security.provider.10=JdkLDAP 79security.provider.11=JdkSASL 80security.provider.12=Apple 81security.provider.13=SunPKCS11 82 83# 84# A list of preferred providers for specific algorithms.

'TLSServer' restricts the algorithm 614# in TLS server certificate chains when server authentication is 615# performed. 'TLSClient' restricts the algorithm in TLS client 616# certificate chains when client authentication is performed. 617# 'SignedJAR' constrains use of certificates in signed jar files. 618# The usage type follows the keyword and more than one usage type can 619# be specified with a whitespace delimiter. 620# Example: "SHA1 usage TLSServer TLSClient" 621# 622# When an algorithm must satisfy more than one constraint, it must be 623# delimited by an ampersand '&'. For example, to restrict certificates in a 624# chain that terminate at a distribution provided trust anchor and contain 625# RSA keys that are less than or equal to 1024 bits, add the following 626# constraint: "RSA keySize <= 1024 & jdkCA". 627# 628# All DisabledAlgorithms expressions are processed in the order defined in the 629# property. This requires lower keysize constraints to be specified 630# before larger keysize constraints of the same algorithm. For example: 631# "RSA keySize < 1024 & jdkCA, RSA keySize < 2048". 632# 633# Note: The algorithm restrictions do not apply to trust anchors or 634# self-signed certificates. 635# 636# Note: This property is currently used by Oracle's PKIX implementation.
