First of all, neither SHA-1 nor anything related to SHA-2 is an "encryption" algorithm. They are hash functions. In SSL, hash functions are used mostly for integrity, not confidentiality, through the HMAC construction. A hash function takes an input of arbitrary length, and produces an output with a fixed length, which is a kind of "digest" of Basic of SHA and MD5 – The Secure Hash Algorithm (SHA) is a family of cryptographic hash functions developed by the U.S. National Institute of Standards and Technology (NIST). The Message Digest (MD5) is a ubiquitous hashing algorithm that was developed by Ron Rivest and is used in a variety of Internet applications today. The RSA signature algorithm. This algorithm is not currently supported. You can use the BCRYPT_RSA_ALGORITHM algorithm to perform RSA signing operations. Standard: PKCS #1 v1.5 and v2.0. BCRYPT_SHA1_ALGORITHM "SHA1" The 160-bit secure hash algorithm. Standard: FIPS 180-2, FIPS 198. BCRYPT_SHA256_ALGORITHM "SHA256" The 256-bit secure hash algorithm. Mar 26, 2020 · SHA-1. SHA stands for Secure Hash Algorithm. The first version of the algorithm was SHA-1, and was later followed by SHA-2 (see below). Whereas MD5 produces a 128-bit hash, SHA1 generates 160-bit hash (20 bytes). In hexadecimal format, it is an integer 40 digits long. What are NIST Encryption Standards for Hash Functions? FIPS 180 specifies the SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224 and SHA-512/256 hash functions. These are sometimes just known as SHA-1 and SHA-2, the number following the hyphen denotes the length of the output. SHA-256 is a cryptographic hash function that is considered to be very secure. It has been standardized in NIST FIPS 180-4. The attack against SHA-1 discovered in 2005 does not affect the security of SHA-256. In order to generate the key for the encryption algorithm, K is transformed using a key derivation function (with a random salt). This

## Encryption algorithm Algorithm description; RSAES_OAEP_SHA_1: PKCS #1 v2.2, Section 7.1. RSA encryption with OAEP Padding using SHA-1 for both the hash and in the MGF1 mask generation function along with an empty label. RSAES_OAEP_SHA_256: PKCS #1, Section 7.1.
