Implementing RSA-SHA1 signature algorithm in Java The RSA-SHA1 signature method uses the RSASSA-PKCS1-v1_5 signature algorithm as defined in [RFC3447] (Jonsson, J. and B. Kaliski, “Public-Key Cryptography Standards (PKCS) #1: RSA Cryptography; Specifications Version 2.1,” .) section 8.2 (more simply known as PKCS#1), using SHA-1 as the hash function for EMSA-PKCS1-v1_5. Cryptography | Android Developers Jun 22, 2020 SHA-1 SSL Certificates SHA-1 was a very popular hashing algorithm used for SSL certificates but is now considered to be insecure. In 2012, a report indicated that it has now become possible to break SHA-1 with enough processing power. In November 2013, Microsoft announced that they wouldn’t be accepting SHA1 certificates after 2016.
