This document: RSA public key and RSA private key. Two key types are employed in the primitives and schemes defined in In this document a recursive approach following The CRT can be applied in a non-recursive as well as a = congruence symbol a = b (mod n) means that the Larger than or equal to the real number x \ceil(.) ceiling function \ceil(x) is the smallest integer \xor bit-wise exclusive-or of two octet strings String of three consecutive octets with hexadecimal Hexadecimal value 48 "(0x)48 09 0e" denotes the XLen (intended) length of the octet string XĠx indicator of hexadecimal representation of an octet orĪn octet string "0x48" denotes the octet with U number of prime factors of the RSA modulus, u >= 2 T_i additional prime factor r_i's CRT coefficient, a SLen length in octets of the EMSA-PSS salt S signature representative, an integer between 0 and n-1 R_i prime factors of the RSA modulus n, including r_1 = p, QInv CRT coefficient, a positive integer less than p such P, q first two prime factors of the RSA modulus n MgfSeed seed from which mask is generated, an octet string MaskLen (intended) length of the octet string mask M message representative, an integer between 0 and n-1 ) least common multiple of a list of nonnegative L optional RSAES-OAEP label, an octet string HLen output length in octets of hash function Hash ) greatest common divisor of two nonnegative integers , uĭP p's CRT exponent, a positive integer such thatĭQ q's CRT exponent, a positive integer such thatĮmBits (intended) length in bits of an encoded message EMĮmLen (intended) length in octets of an encoded message EM Publications and standards, and provide general information aboutĬ ciphertext representative, an integer between 0 andĭ_i additional factor r_i's CRT exponent, a positiveĮ * d_i = 1 (mod (r_i-1)), i = 3.

The organization of this document is as follows: RFC 3447 PKCS #1: RSA Cryptography Specifications February 2003
This document supersedes PKCS #1 version 2.0 but includes The ANSI X9F1 and IEEE P1363 working groups. IEEE-1363-2000 and draft standards currently being developed by The recommendations are intended to be compatible with the standard It is expected that application standardsīased on these specifications may include additional constraints. The recommendations are intended for general application withinĬomputer and communications systems, and as such include a fairĪmount of flexibility. * ASN.1 syntax for representing keys and for identifying the schemes Public-key cryptography based on the RSA algorithm, covering the This document provides recommendations for the implementation of Corrections Made During RFC Publication Process.
