comment Certificate signature with SHA-1 and RSA: where do 1888 bits come from?
Bear with me. When SHA1 is used as a mechanism for generating the hash value from a message, it will produce only 160 bits according to the SHA1 standard. Most X509 Certificates use (PKCS#1 SHA1 with RSA encryption) as the Certificate Signature Algorithm to produce the signature value of length 2048 bits. Thus, 2048 bits includes 160 bits plus 1888 bits which is my confusion! how do they come up with 1888 ?
