I am new to AES GCM, please help how to resolve "AES Decrypt - Authentication tag does not match tag length." this issue.
Hi @SapanJain321, The AES-GCM cipher with a key, a given IV and the ciphertext to be encrypted, returns as result the ciphertext and a tag value (AES_GCM is an AEAD cipher). This tag value must be entered - in the "GCM tag" field - when decrypting the ciphertext using the same key and IV. Try it and let us know your experience.
