summary: IV collision in github.com/bincyber/go-sqlcrypter
description: |-
    There is a risk of an IV collision using the awskms or aesgcm provider. NIST SP
    800-38D section 8.3 states that it is unsafe to encrypt more than 2^32
    plaintexts under the same key when using a random IV. The limit could easily be
    reached given the use case of database column encryption. Ciphertexts are likely
    to be persisted and stored together. IV collision could enable an attacker with
    access to the ciphertexts to decrypt all messages encrypted with the affected
    key.

    The aesgcm provider cannot be fixed without a breaking change, so users should
    not encrypt more than 2^32 values with any key. The awskms package can be fixed
    without a breaking change by switching to a counter-based IV.
