From 053e4edd80f9d15a480585cfa82110ac8543dc97 Mon Sep 17 00:00:00 2001 From: Russ Cox Date: Mon, 21 May 2012 14:10:16 -0400 Subject: [PATCH] crypto/rsa: add SHA-224 hash prefix http://www.rsa.com/rsalabs/node.asp?id=2125: NOTE: A new OID has been defined for the combination of the v1.5 signature scheme and the SHA-224 hash function: sha224WithRSAEncryption OBJECT IDENTIFIER ::= Like the other sha*WithRSAEncryption OIDs in PKCS #1 v2.1, this OID has NULL parameters. The DigestInfo encoding for SHA-224 (see Section 9.2, Note 1) is: (0x)30 2d 30 0d 06 09 60 86 48 01 65 03 04 02 04 05 00 04 1c || H R=golang-dev, agl CC=golang-dev https://golang.org/cl/6208076 --- src/pkg/crypto/rsa/pkcs1v15.go | 1 + 1 file changed, 1 insertion(+) diff --git a/src/pkg/crypto/rsa/pkcs1v15.go b/src/pkg/crypto/rsa/pkcs1v15.go index 8981074b63..a71c82c0f9 100644 --- a/src/pkg/crypto/rsa/pkcs1v15.go +++ b/src/pkg/crypto/rsa/pkcs1v15.go @@ -151,6 +151,7 @@ func nonZeroRandomBytes(s []byte, rand io.Reader) (err error) { var hashPrefixes = map[crypto.Hash][]byte{ crypto.MD5: {0x30, 0x20, 0x30, 0x0c, 0x06, 0x08, 0x2a, 0x86, 0x48, 0x86, 0xf7, 0x0d, 0x02, 0x05, 0x05, 0x00, 0x04, 0x10}, crypto.SHA1: {0x30, 0x21, 0x30, 0x09, 0x06, 0x05, 0x2b, 0x0e, 0x03, 0x02, 0x1a, 0x05, 0x00, 0x04, 0x14}, + crypto.SHA224: {0x30, 0x2d, 0x30, 0x0d, 0x06, 0x09, 0x60, 0x86, 0x48, 0x01, 0x65, 0x03, 0x04, 0x02, 0x04, 0x05, 0x00, 0x04, 0x1c}, crypto.SHA256: {0x30, 0x31, 0x30, 0x0d, 0x06, 0x09, 0x60, 0x86, 0x48, 0x01, 0x65, 0x03, 0x04, 0x02, 0x01, 0x05, 0x00, 0x04, 0x20}, crypto.SHA384: {0x30, 0x41, 0x30, 0x0d, 0x06, 0x09, 0x60, 0x86, 0x48, 0x01, 0x65, 0x03, 0x04, 0x02, 0x02, 0x05, 0x00, 0x04, 0x30}, crypto.SHA512: {0x30, 0x51, 0x30, 0x0d, 0x06, 0x09, 0x60, 0x86, 0x48, 0x01, 0x65, 0x03, 0x04, 0x02, 0x03, 0x05, 0x00, 0x04, 0x40}, -- 2.48.1
