挺实用的jar，用到了就下载 ，下载了就想着分享给大家

java加密工具，非常好用、实用的工具，在java工程中直接调用即可。

包含 bcmail-jdk15on-1.58，bcprov-jdk15on-1.58，bcpkix-jdk15on-1.58 3个jar

org.bouncycastle.util.encoders.Base64 BC实现Base64加解密jar包

Itext加密 出现下面错误 java.lang.NoClassDefFoundError: org/bouncycastle/asn1/ASN1OctetString 则加上这个架包就可以了 bcprov-jdk15on-147.jar

Java加密所需工具bcprov-jdk16-140.jar

解决javax.net.ssl.SSLException: java.lang.RuntimeException: Could not generate DH keypair异常所需jar包

bcprov-ext-jdk15on-1.54.jar、bcprov-jdk15on-1.54.jar和ssl-provider-jvm16-0.2.jar附件下载

放到$JAVA_HOME/jre/lib/ext下 解决：javax.net.ssl.SSLException: java.lang.RuntimeException: Could not generate DH keypair java.security.InvalidAlgorithmParameterException: Prime size must be multiple of 64, and can only range from 512 to 1024 (inclusive)
