The `keytool` and `jarsigner` tools have been updated to warn users when weak cryptographic algorithms are used in keys, certificates, and signed JARs before they are disabled. The weak algorithms are set in the `jdk.security.legacyAlgorithms` security property in the `java.security` configuration file. In this release, the tools issue warnings for the SHA-1 hash algorithm and 1024-bit RSA/DSA keys.
