ECB, CBC, CFB, OFB

Can somebody more experienced than I am explain the strengths and weaknesses of these encryption modes as applied to CAST, IDEA, DES, and Blowfish?

-m mode Set the transfer mode.

Valid ENCRYPTION modes are:

ecb Electronic codebook mode c[i] = f1(K, p[i]) p[i] = f2(K, c[i])

cbc Ciphertext block chaining mode c[i] = f1(K, p[i] ^ c[i-1]) p[i] = f2(K, c[i]) ^ c[i-1]

cfb Ciphertext feeback mode c[i] = f1(K, c[i-1]) ^ p[i] p[i] = f2(K, c[i-1]) ^ c[i]

ofb Output feeback mode h[i] = f1(K, h[i-1]) c[i] = p[i] ^ h[i] p[i] = c[i] ^ h[i]
