Troubleshooting
Problem
The AEADBadTagException is thrown when the cryptographic integrity check on the data fails during decryption. This is commonly seen with AEAD block ciphers like AES in GCM mode. (Example cipher SSL_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256)

Symptom
Sysmptom for this error causes:
a) Data Corruption: Occurs if the ciphertext or associated data is modified or corrupted.
b) Key Mismatch: Using a different key for decryption than was used for encryption.
c) Nonce/IV Reuse: Reusing the nonce or initialization vector for multiple encryptions with the same key.
d) Incorrect Tag Handling: The authentication tag is either incorrect or improperly handled.
b) Key Mismatch: Using a different key for decryption than was used for encryption.
c) Nonce/IV Reuse: Reusing the nonce or initialization vector for multiple encryptions with the same key.
d) Incorrect Tag Handling: The authentication tag is either incorrect or improperly handled.
