A preimage attack on DHA-256 hash function reduced to 37-round and a pseudo collision attack on the func-tion reduced to 39-round were proposed respectively. Based on the meet-in-the-middle attack. the Biclique technique was used to improve the preimage attack from 35-round to 37-round. A 39-round pseudo collision was achieved using the Bi-clique technique. https://parisnaturalfoodes.shop/product-category/deodorant-cream-lavender/
