Findings 1
Use of AES-256-CBC without authentication
NPS-AA51AF9F38B8
The code supports 'aes-256-cbc' mode which lacks authentication (no AAD/AEAD tag), making it vulnerable to padding oracle attacks. However, this is a documented limitation and not a malicious pattern.

|---|---|---|
| dist/config.js | safe | No malicious patterns detected |
| dist/consts.js | safe | No malicious patterns detected |
| dist/index.js | safe | No malicious patterns detected in this ECIES encryption library implementation. |
| dist/keys/PrivateKey.js | safe | The code implements standard elliptic curve private key operations with no malicious patterns such as data exfiltration, credential harvesting, obfuscation, or dynamic execution. |
