Python

Use of insecure MD2, MD4, MD5, or SHA1 hash functions should be avoided. Using more secure algorithms like SHA256 or SHA512.

Use of insecure cipher or cipher mode. Replace with a known secure cipher such as AES.

Use of insecure cipher or cipher mode. Replace with a known secure cipher such as AES.

Cipher used is not secure. It is recommended to replace with a known secure cipher such as AES.

Use of insecure cipher mode such as ECB is not recommended for use in cryptographic protocols at all. In case of ECB, it encrypts identical plaintext blocks into identical ciphertext blocks; and does not hide data patterns well. In some senses, it doesn't provide serious message confidentiality.
