java - JCE - 如何找到活跃的加密服务提供者

转载作者：太空宇宙更新时间：2023-11-03 13:21:46

如我所见document ，JCE 有多个提供者。如何找出默认可用的提供程序？

最佳答案

调用Security.getProviders() ，例如

for (Provider provider : Security.getProviders())
    System.out.printf("%-11s %s%n", provider.getName(), provider.getInfo());

我在 Windows 上的 Oracle Java 9.0.1 上的输出:

SUN         SUN (DSA key/parameter generation; DSA signing; SHA-1, MD5 digests; SecureRandom; X.509 certificates; PKCS12, JKS & DKS keystores; PKIX CertPathValidator; PKIX CertPathBuilder; LDAP, Collection CertStores, JavaPolicy Policy; JavaLoginConfig Configuration)
SunRsaSign  Sun RSA signature provider
SunEC       Sun Elliptic Curve provider (EC, ECDSA, ECDH)
SunJSSE     Sun JSSE provider(PKCS12, SunX509/PKIX key/trust factories, SSLv3/TLSv1/TLSv1.1/TLSv1.2/DTLSv1.0/DTLSv1.2)
SunJCE      SunJCE Provider (implements RSA, DES, Triple DES, AES, Blowfish, ARCFOUR, RC2, PBE, Diffie-Hellman, HMAC)
SunJGSS     Sun (Kerberos v5, SPNEGO)
SunSASL     Sun SASL provider(implements client mechanisms for: DIGEST-MD5, EXTERNAL, PLAIN, CRAM-MD5, NTLM; server mechanisms for: DIGEST-MD5, CRAM-MD5, NTLM)
XMLDSig     XMLDSig (DOM XMLSignatureFactory; DOM KeyInfoFactory; C14N 1.0, C14N 1.1, Exclusive C14N, Base64, Enveloped, XPath, XPath2, XSLT TransformServices)
SunPCSC     Sun PC/SC provider
JdkLDAP     JdkLDAP Provider (implements LDAP CertStore)
JdkSASL     JDK SASL provider(implements client and server mechanisms for GSSAPI)
SunMSCAPI   Sun's Microsoft Crypto API provider
SunPKCS11   Unconfigured and unusable PKCS11 provider

如果您想查看每个提供商提供的服务，试试这个:

for (Provider provider : Security.getProviders()) {
    System.out.printf("%-11s %s%n", provider.getName(), provider.getInfo());
    for (Service service : provider.getServices())
        System.out.printf("  %s: %s%n", service.getType(), service.getAlgorithm());
}

输出
