I'm going to pause this while I figure out if the existing and upcoming ECC profiles will require me to bring this dependency right back... |

Summary
Removed the
bcprov-jdk18on(BouncyCastle Provider) dependency fromstack-core. It is no longer necessary to install a BouncyCastle security provider to use any of the supportedSecurityPolicyvalues.Background
Prior to this change, Eclipse Milo depended on BouncyCastle's provider library (
bcprov-jdk18on) in addition to its PKIX library (bcpkix-jdk18on). The provider dependency was originally needed because certain cryptographic algorithms used by OPC UA security policies were not available in older Java versions' default security providers.However, all cryptographic algorithms required by Milo's supported security policies are now available in modern Java (17+) through the built-in JCA/JCE providers:
RSA/ECB/PKCS1Padding,AES/CBC/NoPadding,HmacSHA1RSA/ECB/OAEPWithSHA-1AndMGF1Padding,AES/CBC/NoPadding,HmacSHA1RSA/ECB/OAEPWithSHA-1AndMGF1Padding,AES/CBC/NoPadding,HmacSHA256RSA/ECB/OAEPWithSHA-1AndMGF1Padding,AES/CBC/NoPadding,HmacSHA256RSA/ECB/OAEPWithSHA-256AndMGF1Padding,AES/CBC/NoPadding,HmacSHA256
