Where U, N, g, s, A, B, M and H(A | M | K) are defined in [RFC2945] (using the SHA1 hash function, i.e., SRP-SHA1). U is a text string, N,g,s,A,B,M and H(A | M | K) are binary items and their binary length (not the encoded length) MUST not exceed 1024 And on Section 3.10.4 Text : Character strings are represented as plain text. Binary items can be encoded using their decimal representation (with or without leading zeros) or hexadecimal representation (e.g., 8190 is 0x1ffe). Upper and lower case letters may be used interchangeably in hexadecimal notation (i.e., 0x1aBc, 0x1AbC, 0X1aBc and 0x1ABC are equivalent). Binary items can also be encoded using the more compact Base64 encoding as specified by [RFC2045] preceded by the 0b.

Based on iSCSI v.09, several key=value pairs are used to exchange SRP parameters and keys. Such as: SRP_N=<N> SRP_g=<g> SRP_s=<s> SRP_A=<A> SRP_B=<B> SRP_M=<M> SRP_HM=<HM> The question is what types of data formats should be used for each key=value pair? Should decimal, hex, base64 or something else be used? It seems iSCSI v.09 or RTF2945 don't specify it. Thanks. Lee Xing Crossroads Systems, Inc.
