+### 🔒 ASN.1 Full Structure Validation (BREAKING CHANGE)
+* **Complete ASN.1 DER parser** for comprehensive key structure verification
+* **OID validation** for algorithms and curves (P-256/P-384 only)
+* **EC point format verification** (uncompressed format 0x04)
+* **SPKI structure validation** with element count and type checking
+* **Key size limits** (50-2000 bytes) to prevent DoS attacks
+* **BIT STRING validation** ensuring unused bits are 0
+* **Fallback support** from P-384 to P-256 for compatibility
+* **High-risk vulnerability fix** where keys with valid headers but modified data could be accepted
+
+### 🔐 Enhanced Key Security
+* **Full structural validation** according to PKCS standards
+* **Complete rewrite** of `validateKeyStructure()` method
+* **Enhanced validation** for all key import/export operations
+* **Military-grade key verification** exceeding previous standards
