Diffie-Hellman MODP size (bits) : 1024 Warning - This is a know static Oakley Group2 modulus. This may make the remote host more vulnerable to the Logjam attack.
Secure Hash Algorithms - Wikipedia Aug 13, 2004 encryption - Sign with RSA-1024 an SHA-256 digest: what is Basically, for RSA-1024, n is 1024. A 1024-bit integer is encoded as 128 bytes, exactly, as per the encoding method described in PKCS#1 (PKCS#1 is very readable and not too long). Whether a n -bit RSA key can be used to sign data with a hash function which produces outputs of length m depends on the details of the padding.

384 and SHA-512, for each 1024-b its block, M (i), which is . Throughout this paper, SHA stands for the Secure Hash Algorithm One (SHA-1 -160 bits hash) [9, 10]. We also assume that all
Generate the SHA512 hash of any string. This online tool allows you to generate the SHA512 hash of any string. The SHA512 hash can not be decrypted if the text you entered is complicated enough. Increased minimum key length to 1024 for XML Signatures The secure validation mode of the XML Signature implementation has been enhanced to restrict RSA and DSA keys less than 1024 bits by default as they are no longer secure enough for digital signatures.
RFC 8017, PKCS #1: RSA Cryptography Specifications Version 2.2 (1024, 2048, 4096) (SHA and SHA-based HMAC and HKDF) Creating a document hash during signing.
Configure Oracle's JDK and JRE Cryptographic Algorithms Prior to this change, the maximum size was 1024 bits. Disable SHA-1 in certificate chains Any TLS server certificate chain containing a SHA-1 certificate (end-entity or intermediate CA) anchored by root CA certificates included by default in Oracle's JDK will be … SHA 1 with RSA for ssl certificate - Information Security
